Give us help from trouble: for vain is the help of man. Again he reverts to the exercise of prayer, or rather is led to it naturally by the very confidence of hope, which we have seen that he entertained. He expresses his conviction, that should God extend his help, it would be sufficient of itself, although no assistance should be received from any other quarter. Literally it reads, Give us help from trouble, and vain is the help of man "O God," as if he had said, "when pleased to put forth thy might, thou needest none to help thee; and when, therefore, once assured of an interest in thy favor, there is no reason why we should desire the aid of man. All other resources of a worldly nature vanish before the brightness of thy power." The copulative in the verse, however, has been generally resolved into the causal particle, and I have not scrupled to follow the common practice. It were well if the sentiment expressed were effectually engraven upon our hearts. Why is it almost universally the case with men that they are either staggered in their resolution, or buoy themselves up with confidences, vain, because not derived from God, but just because they have no apprehension of that salvation which he can extend, which is of itself sufficient, and without which, any earthly succor is entirely ineffectual? In contrasting the help of God with that of man, he employs language not strictly correct, for, in reality, there is no such thing as a power in man to deliver at all. But, in our ignorance, we conceive as if there were various kinds of help in the world, and he uses the word in accommodation to our false ideas. God, in accomplishing our preservation, may use the agency of man, but he reserves it to himself, as his peculiar prerogative, to deliver, and will not suffer them to rob him of his glory. The deliverance which comes to us in this manner through human agency must properly be ascribed to God. All that David meant to assert is, that such confidences as are not derived from God are worthless and vain. And to confirm this position, he declares in the last verse of the psalm, that as, on the one hand, we can do nothing without him, so, on the other, we can do all things by his help. Two things are implied in the expression, through God we shall do valiantly; [1] first, that if God withdraw his favor, any supposed strength which is in man will soon fail; and, on the other hand, that those whose sufficiency is derived from God only are armed with courage to overcome every difficulty. To show that it is no mere half credit which he gives God, he adds, in words which ascribe the whole work to him, that it is he who shall tread down our enemies Thus, even in our controversy with creatures like ourselves, we are not at liberty to share the honor of success with God; and must it not be accounted greater sacrilege still when men set free will in opposition to divine grace, and speak of their concurring equally with God in the matter of procuring eternal salvation? Those who arrogate the least fraction of strength to themselves apart from God, only ruin themselves through their own pride.

1 - Street supposes that this psalm was composed before the battle of Helam, which is recorded in 1 Chronicles 19:16, where David beat the Syrians of Mesopotamia and the Syrians of Zobah; and, farther, that this psalm might have been sung by the armies of Israel when they were marching out to that battle, triumphantly commemorating their former victories, and avowing their hopes of gaining another by the help of the Almighty. On this verse he observes: "it was a constant practice among the bravest nations of the Greeks, for the troops to advance to battle chanting some kind of song." And, after quoting some lines which were sung by the Spartan soldiery, he adds, "The Grecian poet avails himself of the love of glory, and the ties of domestic affection, to animate his troops; but the Hebrew makes use of the more powerful stimulus of religious enthusiasm."

Give us help from trouble - From the troubles which have now come upon us and overwhelmed us.
For vain is the help of man - Margin, salvation. The idea is, that they would look in vain to man to assist them in their present difficulties. They must depend on God alone. What is here said of temporal troubles is true as absolutely in the matter of salvation. When we are burdened with the consciousness of guilt, and trembling under the apprehension of the wrath to come, it is not man that can aid us. Our help is in God alone. Man can neither guide, comfort, pardon, nor save; and in vain should we look to any man, or to all people, for aid. We must look to God alone: to God as the only one who can remove guilt from the soul; who can give peace to the troubled heart; who can deliver us - from condemnation and ruin.

Give us help from trouble: for vain is the help of man - We have done all we can do, and have trusted too much in ourselves; now, Lord, undertake for us.

Give us help from trouble,.... To have trouble is the common lot of all men, but especially of the people of God. They have some troubles which others have not, arising from indwelling sin, Satan's temptations, and the hidings of God's face; and as for outward troubles, they have generally the greatest share of them, which are certain to them by the appointment of God, and the legacy of Christ; though they are needful and for their good, and lie in their way to heaven. But perhaps here is particularly meant the time of trouble, which will be a little before the destruction of antichrist; which will be great, and none like it; will be the time of Jacob's trouble, though he shall be saved out of it, Jeremiah 30:7. This will be the time of the slaying of the witnesses, the hour of temptation, that will try the inhabitants of the Christian world; and when the saints, as they do in all their times of trouble, will seek to the Lord for help, in whom it is, and who has promised it, and gives it seasonably, and which is owing wholly to his own grace and goodness; and therefore it is asked that he would "give" it;
for vain is the help of man: or "the salvation of man" (w); man himself is a vain thing; vanity itself, yea, lighter than vanity; even man at his best state, and the greatest among men; and therefore it is a vain thing to expect help and salvation from men, for indeed there is none in them; only in the Lord God is the salvation of his people, both temporal and spiritual.

Hence he closes with a prayer for success, and an assurance of a hearing.
