Therewith, or, by it, bless we God. It is a clear instance of its deadly poison, that it can thus through a monstrous levity transform itself; for when it pretends to bless God, it immediately curses him in his own image, even by cursing men. For since God ought to be blessed in all his works, he ought to be so especially as to men, in whom his image and glory peculiarly shine forth. It is then a hypocrisy not to be borne, when man employs the same tongue in blessing God and in cursing men. There can be then no calling on God, and his praises must necessarily cease, when evil-speaking prevails; for it is impious profanation of God's name, which the tongue is virulent towards our brethren and pretends to praise him. That he may therefore rightly praise God, the view of evil speaking as to our neighbor must especially be corrected. This particular truth ought also to be borne in mind, that severe censors discover their own virulence, which they suddenly vomit forth against their brethren whatever curses they can imagine, after having in sweet strains offered praises to God. Were any one to object and say, that the image of God in human nature has been blotted out by the sin of Adam; we must, indeed, confess that it has been miserably deformed, but in such a way that some of its lineaments still appear. Righteousness and rectitude, and the freedom of choosing what is good, have been lost; but many excellent endowments, by which we excel the brutes, still remain. He, then, who truly worships and honors God, will be afraid to speak slanderously of man.

Therewith bless we God - We men do this; that is, all this is done by the tongue. The apostle does not mean that the same man does this, but that all this is done by the same organ - the tongue.
Even the Father - Who sustains to us the relation of a father. The point in the remark of the apostle is, the absurdity of employing the tongue in such contradictory uses as to bless one who has to us the relation of a father, and to curse any being, especially those who are made in his image. The word bless here is used in the sense of praise, thank, worship.
And therewith curse we men - That is, it is done by the same organ by which God is praised and honored.
Which are made after the similitude of God - After his image, Genesis 1:26-27. As we bless God, we ought with the same organ to bless those who are like him. There is an absurdity in cursing men who are thus made, like what there would be in both blessing and cursing the Creator himself.

Therewith bless we God - The tongue is capable of rehearsing the praises, and setting forth the glories, of the eternal King: what a pity that it should ever be employed in a contrary work! It can proclaim and vindicate the truth of God, and publish the Gospel of peace and good will among men: what a pity that it should ever be employed in falsehoods, calumny, or in the cause of infidelity!
And therewith curse we men - In the true Satanic spirit, many pray to God, the Father, to destroy those who are objects of their displeasure! These are the common swearers, whose mouths are generally full of direful imprecations against those with whom they are offended.
The consideration that man is made after the image of God should restrain the tongue of the swearer; but there are many who, while they pretend to sing the high praises of God, are ready to wish the direst imprecations either on those who offend them, or with whom they choose to be offended.

(6) Therewith bless we God, even the Father; and therewith curse we men, which are made after the (7) similitude of God.
(6) Among other faults of the tongue, the apostle chiefly reproves slandering and speaking evil of our neighbours, even in those especially who otherwise will seem godly and religious. (7) He denies by two reasons, that God can be praised by the man who uses cursed speaking, or slandering: first because man is the image of God and whoever does not reverence him, does not honour God.

Therewith bless we God, even, the Father,.... Of Jesus Christ, and of spirits, and of mercies: this is the instrument that is used in blessing God daily every meal that is eaten; and in joining with the saints, though only verbally and outwardly, in blessing God for all spiritual blessings in Christ, both in prayer, and in singing psalms:
and therewith curse we men: make imprecations, and wish evils upon them:
which are made after the similitude of God as man was originally, Genesis 1:26 and though sin has greatly defaced it, yet there are still some remains of it: and now, what an absurd and monstrous thing is this, that one and the same instrument should be used in blessing God, the Father of all creatures, and in cursing his children, his offering, as all men are by creation, and bear some resemblance to him.

God--The oldest authorities read, "Lord." "Him who is Lord and Father." The uncommonness of the application of "Lord" to the Father, doubtless caused the change in modern texts to "God" (James 1:27). But as Messiah is called "Father," Isaiah 9:6, so God the Father is called by the Son's title, "Lord": showing the unity of the Godhead. "Father" implies His paternal love; "Lord," His dominion.
men, which--not "men who"; for what is meant is not particular men, but men genetically [ALFORD].
are made after . . . similitude of God--Though in a great measure man has lost the likeness of God in which he was originally made, yet enough of it still remains to show what once it was, and what in regenerated and restored man it shall be. We ought to reverence this remnant and earnest of what man shall be in ourselves and in others. "Absalom has fallen from his father's favor, but the people still recognize him to be the king's son" [BENGEL]. Man resembles in humanity the Son of man, "the express image of His person" (Hebrews 1:3), compare Genesis 1:26; 1-John 4:20. In the passage, Genesis 1:26, "image" and "likeness" are distinct: "image," according to the Alexandrians, was something in which men were created, being common to all, and continuing to man after the fall, while the "likeness" was something toward which man was created, to strive after and attain it: the former marks man's physical and intellectual, the latter his moral pre-eminence.

Therewith bless we God. Its opposite uses are shown. We use it to pray and to bless God, and, sometimes, the same tongue will be used to curse his creatures. James rebuked evils that he had observed.
Out of the same mouth. These utterly inconsistent things come out of the same mouth.
Doth a fountain. In nature such incongruity is not shown. A fountain does not give out two kinds of waters.
Can the fig tree. Neither does a tree bear two opposite kinds of fruits. Nor should the mouth bear blessing and cursing, good and evil.

Men made after the likeness of God - Indeed we have now lost this likeness; yet there remains from thence an indelible nobleness, which we ought to reverence both in ourselves and others.
