And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell.

And the tongue is a fire: the world of iniquity among our members is the tongue, which defileth the whole body, and setteth on fire the wheel of nature, and is set on fire by hell.

And the tongue is a fire, a world of iniquity. The tongue is placed among our members, which defileth the whole body, and inflameth the wheel of our nativity, being set on fire by hell.

and the tongue is fire, the world of unrighteousness; the tongue is set in our members, the defiler of the whole body, and which sets fire to the course of nature, and is set on fire of hell.

and the tongue is a fire, the world of the unrighteousness, so the tongue is set in our members, which is spotting our whole body, and is setting on fire the course of nature, and is set on fire by the gehenna.

And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defiles the whole body, and sets on fire the course of nature; and it is set on fire of hell.

And the tongue is a fire. That world of iniquity, the tongue, is placed within us spotting and soiling our whole nature, and setting the whole round of our lives on fire, being itself set on fire by Gehenna.

And the tongue is a fire; it is the power of evil placed in our bodies, making all the body unclean, putting the wheel of life on fire, and getting its fire from hell.

And the tongue is a fire. The world of iniquity among our members is the tongue, which defiles the whole body, and sets on fire the course of nature, and is set on fire by hell.

And so the tongue is like a fire, comprising all iniquity. The tongue, stationed in the midst of our body, can defile the entire body and inflame the wheel of our nativity, setting a fire from Hell.

And the tongue is like a spark. It is a world of unrighteousness among the parts of our body. It contaminates the whole body; it sets the whole course of our existence on fire, and is itself set on fire by the flames of Gehenna.

Et lingua ignis est, et mundus iniquitatis: sic inquam lingua constituta est in membris nostris, inquinans totum corpus, inflammans rotam nativitatis, et inflammatur a gehenna.

By adding that it is a world of iniquity, it is the same as though he had called it the sea or the abyss. And he suitably connects the smallness of the tongue with the vastness of the world; according to this meaning, A slender portion of flesh contains in it the whole world of iniquity. So is the tongue. He explains what he meant by the term world, even because the contagion of the tongue spreads through every part of life; or rather he shews what he understood by the metaphor fire, even that the tongue pollutes the whole man. He however immediately returns to the fire, and says, that the whole course of nature is set on fire by the tongue. And he compares human life to a course or a wheel: and genesis, as before, he takes for nature, (James 1:23.) The meaning is, that when other vices are corrected by age or by the succession of time, or when at least then do not possess the whole man, the vice of the tongue spreads and prevails over every part of life; except one prefers to take setting on fire as signifying a violent impulse, for we call that fervid which is accompanied with violence. And thus Horace speaks of wheels, for he calls chariots in battle fervid, on account of their rapidity. The meaning then would be, that the tongue is like untamed horses; for as these draw violently the chariots, so the tongue hurries a man headlong by its own wantonness. [1] When he says that it is set on fire by hell, it is the same as though he had said, that the outrageousness of the tongue is the flame of the infernal fire. [2] For as heathen poets imagined that the wicked are tormented by the torches of the Furies; so it is true, that Satan by the fans of temptations kindles the fire of all evils in the world: but James means, that fire, sent by Satan, is most easily caught by the tongue, so that it immediately burns; in short, that it is a material fitted for receiving or fostering and increasing the fire of hell.

Footnotes

1 - "The course of nature," or the compass of nature, that is, all that is included in nature, means evidently the same with "the whole body" in the preceding clause. There is no sense, compatible with the passage, in what some have suggested, "the whole course of life;" for what idea is conveyed, when we say that the tongue inflames or sets in a flame the whole course of life? But there is an intelligible meaning, when it is said, that the tongue sets in a flame the whole machinery of our nature, every faculty that belongs to man.

2 - "A bad tongue is the organ of the devil." -- Estius.

And the tongue is a fire - In this sense, that it produces a "blaze," or a great conflagration. It produces a disturbance and an agitation that may be compared with the conflagration often produced by a spark.
A world of iniquity - A little world of evil in itself. This is a very expressive phrase, and is similar to one which we often employ, as when we speak of a town as being a world in miniature. We mean by it that it is an epitome of the world; that all that there is in the world is represented there on a small scale. So when the tongue is spoken of as being "a world of iniquity," it is meant that all kinds of evil that are in the world are exhibited there in miniature; it seems to concentrate all sorts of iniquity that exist on the earth. And what evil is there which may not be originated or fomented by the tongue? What else is there that might, with so much propriety, be represented as a little world of iniquity? With all the good which it does, who can estimate the amount of evil which it causes? Who can measure the evils which arise from scandal, and slander, and profaneness, and perjury, and falsehood, and blasphemy, and obscenity, and the inculcation of error, by the tongue? Who can gauge the amount of broils, and contentions, and strifes, and wars, and suspicions, and enmities, and alienations among friends and neighbors, which it produces? Who can number the evils produced by the "honeyed" words of the seducer; or by the tongue of the eloquent in the maintenance of error, and the defense of wrong? If all men were dumb, what a portion of the crimes of the world would soon cease! If all men would speak only that which ought to be spoken, what a change would come over the face of human affairs!
So is the tongue among our members, that it defileth the whole body - It stains or pollutes the whole body. It occupies a position and relation so important in respect to every part of our moral frame, that there is no portion which is not affected by it. Of the truth of this, no one can have any doubt. There is nothing else pertaining to us as moral and intellectual beings, which exerts such an influence over ourselves as the tongue. A man of pure conversation is understood and felt to be pure in every respect; but who has any confidence in the virtue of the blasphemer, or the man of obscene lips, or the calumniator and slanderer? We always regard such a man as corrupt to the core.
And setteth on fire the course of nature - The margin is "the wheel of nature." The Greek word also (τροχός trochos) means "a wheel," or any thing made for revolving and running. Then it means the course run by a wheel; a circular course or circuit. The word rendered "nature" (γένεσις genesis), means "procreation, birth, nativity;" and therefore the phrase means, literally, the wheel of birth - that is, the wheel which is set in motion at birth, and which runs on through life. - Rob. Lex. sub voce γένεσεως geneseōs. It may be a matter of doubt whether this refers to successive generations, or to the course of individual life. The more literal sense would be that which refers to an individual; but perhaps the apostle meant to speak in a popular sense, and thought of the affairs of the world as they roll on from age to age, as all enkindled by the tongue, keeping the world in a constant blaze of excitement. Whether applied to an individual life, or to the world at large, every one can see the justice of the comparison. One naturally thinks, when this expression is used, of a chariot driven on with so much speed that its wheels by their rapid motion become self-ignited, and the chariot moves on amidst flames.
And it is set on fire of hell - Hell, or Gehenna, is represented as a place where the fires continually burn. See the notes at Matthew 5:22. The idea here is, that that which causes the tongue to do so much evil derives its origin from hell. Nothing could better characterize much of that which the tongues does, than to say that it has its origin in hell, and has the spirit which reigns there. The very spirit of that world of fire and wickedness - a spirit of falsehood, and slander, and blasphemy, and pollution - seems to inspire the tongue. The image which seems to have been before the mind of the apostle was that of a torch which enkindles and burns everything as it goes along - a torch itself lighted at the fires of hell. One of the most striking descriptions of the woes and curses which there may be in hell, would be to portray the sorrows caused on the earth by the tongue.

The tongue is a fire - It is often the instrument of producing the most desperate contentions and insurrections.
A world of iniquity - This is an unusual form of speech, but the meaning is plain enough; World signifies here a mass, a great collection, an abundance. We use the term in the same sense - a world of troubles, a world of toil, a world of anxiety; for great troubles, oppressive toil, most distressing anxiety. And one of our lexicographers calls his work a world of words; i.e. a vast collection of words: so we also say, a deluge of wickedness, a sea of troubles; and the Latins, oceanus malorum, an ocean of evils. I do not recollect an example of this use of the word among the Greek writers; but in this sense it appears to be used by the Septuagint, Proverbs 17:6 : Του πιστου ὁλος ὁ κοσμος των χρηματων, του δε απιστου ουδε οβολος, which may be translated, "The faithful has a world of riches, but the unfaithful not a penny." This clause has nothing answering to it in the Hebrew text. Some think that the word is thus used, 2-Peter 2:5 : And brought the flood, κοσμῳ ασεβων, on the multitude of the ungodly. Mr. Wakefield translates the clause thus: The tongue is the varnisher of injustice. We have seen that κοσμοςsignifies adorned, elegant, beautiful, etc., but I can scarcely think that this is its sense in this place. The Syriac gives a curious turn to the expression: And the tongue is a fire; and the world of iniquity is like a wood. Above, the same version has: A little fire burns great woods. So the world of iniquity is represented as inflamed by the wicked tongues of men; the world being fuel, and the tongue a fire.
So is the tongue among our members - I think St. James refers here to those well known speeches of the rabbins, Vayikra Rabba, sec. 16, fol. 159. "Rabbi Eleazar said, Man has one hundred and forty-eight members, some confined, others free. The tongue is placed between the jaws; and from under it proceeds a fountain of water, (the great sublingual salivary gland), and it is folded with various foldings. Come and see what a flame the tongue kindles! Were it one of the unconfined members, what would it not do?" The same sentiment, with a little variation, may be found in Midrash, Yalcut Simeoni, par. 2, fol. 107; and in Erachin, fol. xv. 2, on Psalm 120:3 : What shall be given unto thee, or what shall be done unto thee, thou false tongue? "The holy blessed God said to the tongue: All the rest of the members of the body are erect, but thou liest down; all the rest are external, but thou art internal. Nor is this enough: I have built two walls about thee; the one bone, the other flesh: What shall be given unto thee, and what shall be done unto thee, O thou false tongue?"
Setteth on fire the course of nature - Φλογιζουσα τον τροχον της γενεσεως· And setteth on fire the wheel of life. I question much whether this verse be in general well understood. There are three different interpretations of it:
1. St. James does not intend to express the whole circle of human affairs, so much affected by the tongue of man; but rather the penal wheel of the Greeks, and not unknown to the Jews, on which they were accustomed to extend criminals, to induce them to confess, or to punish them for crimes; under which wheels, fire was often placed to add to their torments. In the book, De Maccabaeis, attributed to Josephus, and found in Haverkamp's edition, vol. ii., p. 497-520, where we have the account of the martyrdom of seven Hebrew brothers, in chap. ix, speaking of the death of the eldest, it is said: Ανεβαλον αυτον επι τον τροχοι - περι ὁν κατατεινομενος· "They cast him on the wheel, over which they extended him; πυρ ὑπεστρωσαν και διηρεθισαν τον τροχον προσεπικατατεινοντες· they put coals under it, and strongly agitated the wheel." And of the martyrdom of the sixth brother it is said, cap. 11: Παρηγον επι τον τροχον, εφ' οὑ κατατεινομενος εκμελως και εκσφονδυλιζομενος ὑπεκαιετο, και οβελισκους δε οξεις πυρωσαντες, τοις νοτοις προσεφερον, και τα πλευρα διαπειραντες αυτου, και τα σπλαγχνα διεκαιον· They brought him to the wheel, on which, having distended his limbs, and broken his joints, they scorched him with the fire placed underneath; and with sharp spits heated in the fire, they pierced his sides, and burned his bowels.
The fire and the wheel are mentioned by Achilles Tatius, lib. 7, p. 449. "Having stripped me of my garments, I was carried aloft, των μεν μαστιγας κομιζοντων, των δε πυρ και τροχον, some bringing scourges, others the fire and the wheel." Now as γενεσις often signifies life, then the wheel of life will signify the miseries and torments of life. To set on fire the wheel of life is to increase a man's torments; and to be set on fire from hell implies having these miseries rendered more active by diabolic agency; or, in other words, bad men, instigated by the devil, through their lies and calumnies, make life burdensome to the objects of their malicious tongues. The wheel and the fire, so pointedly mentioned by St. James, make it probable that this sort of punishment might have suggested the idea to him. See more in Kypke.
2. But is it not possible that by the wheel of life St. James may have the circulation of the blood in view? Angry or irritating language has an astonishing influence on the circulation of the blood: the heart beats high and frequent; the blood is hurried through the arteries to the veins, through the veins to the heart, and through the heart to the arteries again, and so on; an extraordinary degree of heat is at the same time engendered; the eyes become more prominent in their sockets; the capillary vessels suffused with blood; the face flushed; and, in short, the whole wheel of nature is set on fire of hell. No description can be more natural than this: but it may be objected that this intimates that the circulation of the blood was known to St. James. Now supposing it does, is the thing impossible? It is allowed by some of the most judicious medical writers, that Solomon refers to this in his celebrated portraiture of old age, particularly in Ecclesiastes 12:6 : "Or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern." Here is the very wheel of life from which St. James might have borrowed the idea; and the different times evidently refer to the circulation of the blood, which might be as well known to St. James as the doctrine of the parallax of the sun. See on James 1:17 (note).
3. It is true, however, that the rabbins use the term גלגל תולדות gilgal toledoth, "the wheel of generations," to mark the successive generations of men: and it is possible that St. James might refer to this; as if he had said: "The tongue has been the instrument of confusion and misery through all the ages of the world." But the other interpretations are more likely.

And the tongue [is] a fire, a (b) world of iniquity: so is the tongue among our members, that it defileth the whole body, and (c) setteth on fire the course of nature; and it is set on fire of hell.
(b) A heap of all mischiefs.
(c) It is able to set the whole world on fire.

And the tongue is a fire,.... It is like to fire, very useful in its place, to warm and comfort; so is the tongue in Christian conversation, and in the ministry of the word; the hearts of God's children burn within them, while they are talking together, and while the Scriptures of truth are opening to them; but as fire should be carefully watched, and kept, so should men take heed to their ways, that they sin not with their tongue, and keep their tongue from evil, and their lips from speaking guile; for as fire kindles and rises up into a flame, so unchaste, angry, and passionate words, stir up the flame of lust, anger, envy, and revenge; and as fire is of a spreading nature, so are lies, scandal, and evil reports vented by the tongue; and as fire devours all that comes in its way, such are the words of an evil tongue; and therefore are called devouring words, Psalm 52:4 they devour the good names of men, and corrupt their good manners, and destroy those who make use of them; and what wood is to fire, and coals to burning coals, that are whisperers, tale bearers, backbiters, and contentious persons to strife, Proverbs 26:20
a world of iniquity; that is, as the world is full of things, and full of sin, for it lies in wickedness, so is the tongue full of iniquity; there is a world of it in it; it abounds with it; it cannot well be said how much sin is in it, and done, or occasioned by it; as blasphemy against God, Father, Son, and Spirit; cursing of men, imprecations on themselves, their souls, and bodies, and on others, with a multitude of profane and dreadful oaths; obscene, filthy, and unchaste words; angry, wrathful, and passionate ones; lies, flatteries, reproaches, backbitings, whisperings, tale bearings, &c. And the Jews say, that he that uses an evil tongue multiplies transgression, and that it is equal to idolatry, adultery, and murder (h), and the cause of all sin; and which they express by way of fable, in this manner (i):
"when Adam sinned, God laid hold on him, and slit his tongue into two parts, and said unto him, the wickedness which is, or shall be in the world, thou hast begun with an evil tongue; wherefore I will make all that come into the world know that thy tongue is the cause of all this.''
The Syriac version renders this clause thus, "and the world of iniquity is as wood"; or the branch of a tree; the tongue is fire, and a wicked world is fuel to it.
So is the tongue amongst our members, that it defileth the whole body: the body politic, a whole nation, filling it with contention, strife, division, and confusion; and the ecclesiastical body, the church, by sowing discord, fomenting animosities, making parties, and spreading errors and heresies, whereby the temple of God is defiled; and the natural body, and the several members of it, even the whole person of a man, soul and body, bringing upon him a blot of infamy and reproach never to be wiped off; as for instance, the vice of the tongue, lying, does; and oftentimes through the tongue, the actions done in the body, which seem good, are quite spoiled:
and setteth on fire the course of nature, or "wheel of nature": the natural body, as before, in which there is a continual rotation or circulation of the blood, by which it is supported; this is the wheel broken at the cistern at death, in Ecclesiastes 12:6 or the course of a man's life and actions, yea, of all generations, and the vicissitudes and changes which have happened in them, on which the tongue has a great influence; and so the Syriac version renders it, "and sets on fire the series of our genealogies, or our generations, which run like wheels": or it may intend the frame of nature, the whole fabric of the universe, and the general conflagration of it, which will be owing to the tongue; or because men's tongues are against the Lord, to provoke the eyes of his glory, because of the hard speeches which ungodly sinners have spoken against Christ and his people, of which they will be convinced by flames of fire about them:
and it is set on fire of hell; that is, by the devil; for as heaven sometimes is put for God, who dwells in heaven, Matthew 21:25 so hell is put for the devil, whose habitation it is; see Matthew 16:18, and the sense is, that the tongue is influenced, instigated, and stirred up by Satan, to speak many evil things, and it will be hereafter set on fire in hell, as the tongue of the rich man in Luke 16:24. To which purpose are those words of the Talmud (k);
"whoever uses an evil tongue, the holy blessed God says to hell, I concerning him above, and thou concerning him below, will judge him, as it is said, Psalm 120:3. "What shall be done to thee, thou false tongue? sharp arrows of the mighty, with coals of juniper", there is no arrow but the tongue, according to Jeremiah 9:8 and there is no mighty one but God, Isaiah 42:13 "coals of juniper", , these are hell.''
