So are the paths of all that forget God - This is clearly a part of the quotation from the sayings of the ancients. The word "paths" here means ways, acts, doings. They who forget God are like the paper-reed. They seem to flourish, but they have nothing that is firm and substantial. As the paper-reed soon dies, as the flag withers away before any other herb, so it will be with the wicked, though apparently prosperous.
And the hypocrite's hope shall perish - This important sentiment, it seems, was known in the earliest periods of the world; and if the supposition above be correct, that this is a fragment of a poem which had come down from far distant times, it was probably known before the flood. The passage requires no particular philological explanation, but it is exceedingly important. We may remark on it,
(1) That there were hypocrites even in that early age of the world. They are confined to no period, or country, or religious denomination, or profession. There are hypocrites in religion - and so there are in politics, and in business, and in friendship, and in morals. There arc pretended friends, and pretended patriots, and pretended lovers of virtue, whose hearts are false and hol ow, just as there are pretended friends of religion. Wherever there is genuine coin, it will be likely to be counterfeited; and the fact of a counterfeit is always a tribute to the intrinsic worth of the coin - for who would be at the pains to counterfeit that which is worthless? The fact that there are hypocrites in the church, is an involuntary tribute to the excellency of religion.
(2) The hypocrite has a hope of eternal life. This hope is founded on various things. It may be on his own morality; it may be on the expectation that he will be able to practice a deception; it may be on some wholly false and unfounded view of the character and plans of God. Or taking the word "hypocrite" in a larger sense to denote anyone who pretends to religion and who has none, this hope may be founded on some change of feeling which he has had, and which he mistook for religion; on some supposed vision which he had of the cross or of the Redeemer, or on the mere subsiding of the alarm which an awakened sinner experiences, and the comparative peace consequent on that. The mere cessation of fear produces a kind of peace - as the ocean is calm and beautiful after a storm - no matter what may be the cause, whether it be true religion or any other cause. Many a sinner, who has lost his convictions for sin in any way, mistakes the temporary calm which succeeds for true religion, and embraces the hope of the hypocrite.
(3) That hope will perish. This may occur in various ways.
(a) It may die away insensibly, and leave the man to be a mere professor of religion - a formalist, without comfort, usefulness, or peace.
(b) It may be taken away in some calamity by which God tries the soul, and where the man will see that he has no religion to sustain him.
(c) It may occur under the preaching of the gospel, when the hypocrite may be convinced that he is destitute of vital piety, and has no true love to God.
(d) It may be on a bed of death - when God comes to take away the soul, and when the judgment-seat appears in view.
(e) Or it will be at the bar of God. Then the hope of the hypocrite will certainly be destroyed. Then it will be seen that he had no true religion, and then he will be consigned to the awful doom of him who in the most solemn circumstances lived to deceive, and who assumed the appearance of that which he had the strongest reason to believe he never possessed. Oh! how important it is for every professor of religion to examine himself, that he may know what is the foundation of his hope of heaven!

So are the paths - The papyrus and the rush flourish while they have a plentiful supply of ooze and water; but take these away, and their prosperity is speedily at an end; so it is with the wicked and profane; their prosperity is of short duration, however great it may appear to be in the beginning. Thou also, O thou enemy of God, hast flourished for a time; but the blast of God is come upon thee, and now thou art dried up from the very roots.
The hypocrite's hope shall perish - A hypocrite, or rather profligate, has no inward religion, for his heart is not right with God; he has only hope, and that perishes when he gives up the ghost. This is the first place in which the word hypocrite occurs, or the noun חנף chaneph, which rather conveys the idea of pollution and defilement than of hypocrisy. A hypocrite is one who only carries the mask of godliness, to serve secular purposes; who wishes to be taken for a religionist, though he is conscious he has no religion. Such a person cannot have hope of any good, because he knows he is insincere: but the person in the text has hope; therefore hypocrite cannot be the meaning of the original word. But all the vile, the polluted, and the profligate have hope; they hope to end their iniquities before they end life; and they hope to get at last to the kingdom of heaven. Hypocrite is a very improper translation of the Hebrew.

So are the paths of all that forget God,.... Who forget that there is a God; he is not in all, and scarce in any of their thoughts, and they live without him in the world; who forget the works of God, of creation and providence, in which there is a glorious display of his being and perfections; who forget the benefits and blessings of his goodness they are every day partakers of, and are not thankful for them; and who forget the word, worship, and ordinances of God, and follow after and observe lying vanities, idols, and the works of men's hands, and worship them, being unmindful of the rock of their salvation: now such men, as well as the hypocrites in the next clause, are like bulrushes and flags, or sedge, being unfruitful, useless, and unprofitable; and, for their sensuality and worldly mindedness, standing in the mire and clay of an unregenerate state, and of carnal and worldly lusts; and though, especially the latter, may carry their heads high in a profession of religion, and make a fair show in the flesh while it is a time of outward prosperity with them, but when tribulation arises on the account of religion, they are presently offended, and apostatize; being destitute of the true grace of God, and having the root of the matter in them, they wither of themselves; they soon drop their profession in the view of all good men, comparable to herbs and green grass, which abide in their verdure, when the other are gone and are seen no more:
and the hypocrite's hope shall perish; who are either the same with those before described, who, being in prosperous circumstances, forget the God of their mercies they make a profession of, like Jeshurun of old, or different persons, as Bar Tzemach thinks, the former designing open profane sinners, these secret ones, under the appearance of good men: an "hypocrite" is one whose inside is not as his outside, as the Jews say; who is outwardly righteous, but inwardly wicked; has a form of godliness, but not the power of it; a name to live, but dead; that makes a show of religion and devotion, attending the worship and ordinances of God in an external way, as if he had great delight in him and them, when his heart is removed far from him: and such have their "hope", for the present, of being in the favour of God, and of future happiness, which is founded on their outward prosperity their esteem among men, and more especially their external righteousness, and profession of religion; but this will "perish", even both the ground of their hope, the riches and righteousness, which come to nothing, and the hope that is built thereupon sinks into despair; if not in life, as it sometimes does, yet always at death, see Job 11:20; Bildad seems to have Job in view here, whom he esteemed an hypocrite.

paths--so "ways" (Proverbs 1:19).
all that forget God--the distinguishing trait of the godless (Psalm 9:17; Psalm 50:22).

Paths - Of wicked men. By their paths he doth not understand their manner of living, but the events which befall them, God's manner of dealing with them.
