Psalms 106:8

8And saved them The prophet here teaches what any one could easily learn from the preceding sentence, that the Israelites were saved, not on account of their deserving to be so, but because God had a regard to his own glory. That obstacle being removed, God went on to accomplish that deliverance which he had commenced, in order that his holy name might not become a reproach among the heathen. Besides, we must not overlook the antithesis between the name of God and the merits of men, because God, out of a regard to his own glory, can find in us no cause wherefore he should be moved to save us. The inestimable kindness of God, which, for the sake of a people so perverse, altered the usual order of nature, is more illustriously displayed by the account which is afterwards given of the means by which they were preserved. When he says that the sea was rebuked, he extols the power of God, at whose command and will the sea was dried up — the waters receded, so that a free passage was opened up between the opposite heaps of waters. With the design of magnifying the miracle, he employs a similitude, which, in all likelihood, was drawn from Isaiah; for in the sixty-third chapter and thirteenth verse, he says, “Thou hast made thy people to walk through the deeps, as an horse in the wilderness, that he might not stumble.” When the people walked through the sea as upon a dry plain, the prophet informs us that this was done solely by the astonishing power of God. It is quite possible, that in the desert in which the people wandered, there was many an abyss, the path rugged, and many a hill and dale and ragged rock. But it cannot be doubted that the prophet extols the power of God in the passage through the sea, and enhances it by this consideration, that the path through that deep sea was smooth. Besides, he gives greater strength to the miracle in saying that their enemies were drowned; because, when the sea afforded a free passage to the children of Israel, and covered and engulfed the Egyptians, sothat not one of them escaped alive, whence proceeded this instantaneous difference, but from this, that God made a distinction between the one people and the other?
