He who fashioned their hearts altogether. It appears that this is added for the express purpose of assuredly persuading believers, that, however the wicked might craftily, deceitfully, and by secret stratagems, attempt to withdraw themselves from God's sight, and hide themselves in caverns, yet his eyes would penetrate into their dark hiding-places. And the Psalmist argues from the very creation that God cannot but bring men's devices and doings into reckoning and judgment; because, though each man has intricate recesses concealed in his bosom, so that there is a wonderful diversity of different minds in this respect, and this great variety creates a most confounding obscurity; yet the eyes of God cannot be dazzled and darkened, so that he may not be a competent judge and take cognisance of his own work. By the adverb together, therefore, he does not mean that the hearts of men were formed at the same moment of time; but that all of them were fashioned even to one, and without a single exception; so that those manifest great folly who attempt to hide, or to withdraw the knowledge of their hearts from him who framed them. The discourse may also be understood as meaning, that men cannot, by the erring devices of their own thoughts, diminish the authority of God over them, so that he may not govern by his secret providence the events which seem to them to happen by chance. We see, indeed, he in forming their vain hopes, they despoil God of his power, and transfer it to the creatures, at one time to this object, and at another time to that, conceiving that they have no need of his aid, so long as they are furnished with outward means and helps to protect themselves. It therefore follows, A king is not saved for the multitude of his host, etc By this the inspired writer means to teach us, that the safety of men's lives depends not upon their own strength, but upon the favor of God. He names particularly kings and giants rather than others; because, as they are not of the common class of men, but of a higher condition, they appear to themselves to be beyond the reach of all danger from darts, and if any adversity befall them, they promise themselves an easy deliverance from it. In short, intoxicated with a presumptuous confidence of their own strength, they scarcely think themselves mortal. They are still more hardened in this pride by the foolish admiration of the common people, who stand amazed at the greatness of their power. If, therefore, neither a king is saved by his troops, nor a giant by his strength, when they are exposed to danger, in vain do mankind neglect the providence of God, and look around them for human help. From this it follows, that the condition, both of the strong and the weak, is miserable, until they learn to rely on the protection of God.

He fashioneth their hearts alike - That is, one as well as another; or, one as really as another. No one is exempt from his control, or from all that is implied in the word "fashioneth." The meaning is not that their hearts are made to "resemble" each other, or to be "like" each other, whether in goodness or in wickedness - but that all alike "are" made by him. The idea in the word "fashioneth" here is not that of "creating," in the sense that He "makes" the heart by his own power what it is, whether good or bad; but that, as he has "formed" the hearts of all people, he must see what is in the heart, or must behold all the purposes and thoughts of people. The Maker of the human heart must understand what is in it; and, therefore, He must have a clear understanding of the purposes and designs of human beings. This idea is carried out in the latter member of the sentence, "he considereth all their works," and is substantially the same as in the expression Psalm 94:9, "He that planted the ear, shall he not hear? He that formed the eye, shall he not see?"
He considereth all their works - He understands all that they do; he marks, or attends to, all that is done by them. The purpose here is to state the universal sovereignty of God. He made all things; He presides over all things; He sees all things; He is the source of safety and protection to all.

He fashioneth their hearts alike - He forms their hearts in unity; he has formed them alike; they are all the works of his hands: and he has formed them with the same powers, faculties, passions, etc.; body and spirit having the same essential properties in every human being.

He (k) fashioneth their hearts alike; he considereth all their works.
(k) Therefore he knows their wicked enterprises.

He fashioneth their hearts alike,.... The Lord is the former and fashioner of the heart, spirit, or soul of man, even of all hearts and spirits; whence he is called the Father of spirits, Hebrews 12:9; see Zac 12:1; and he is the former of them alike; which seems to intimate as if all seals were alike, as they are made by the Lord; and it may be the difference there appears to be between them afterwards, nay be owing to the make and constitution of their bodies, to their education, and different situation, circumstances, and advantages in life, whereby the hearts of some may be more opened and enlarged than others. Some render it "together", or "altogether" (g); which must not be understood of time, as if they were all made at once, but of equality; the one was made by him as well as the other; he is the fashioner of one and all of them, every whit of them; they are wholly fashioned by him, and all that is in them, all the powers and faculties of the soul; and by him only, and not by the instrumentality of another; for souls are created, not generated; they are produced out of nothing, and not out of pre-existent matter, as bodies; parents contribute somewhat to the bodies of their children, but not anything to their souls. God only "is the God of the spirits of all flesh", Numbers 16:22; some translate the word "singly" (h); one by one, one after another in the several ages of time; for he continues to fashion them, and is always doing it; see Zac 12:1. And he forms the hearts of his own people anew for himself, for his own glory; he forms Christ in them, and every grace of his Spirit; he forms them into one, and knits and unites them together in love, and makes them like to one another; for as face answers to face in water, so do the hearts and experiences of the saints one to another, Proverbs 27:19; all which he does wholly and alone; and since he fashions the hearts of all men in every sense, he must know them, which is the design of this expression; he knows the hearts of wicked men, and all the wickedness that is in them; he knows the hearts of good men, the worst that is in them, and also the best, which he himself has put there;
he considereth all their works; the works of evil men, not only their more open ones, but their more secret ones, and will bring them into judgment; and the works of good men, even their good works, which he will remember and reward in a way of grace.
(g) "simul", Musculus, Gejerus; so Ainsworth. (h) Sept. "sigillatim", V. L.
