And 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, so that 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?

Nevertheless, he saved them for his name's sake - For the promotion of his own honor and glory; that it might be seen that he is powerful and merciful. This is constantly given as the reason why God saves people; why he forgives sin; why he redeems the soul; why he delivers from danger and from death. Compare Ezekiel 36:22, Ezekiel 36:32; Isaiah 37:35; Isaiah 43:25; Isaiah 48:9; Jeremiah 14:7; Psalm 6:4; Psalm 23:3; Psalm 25:11; Psalm 31:16; Psalm 44:26. This is the highest reason which can be assigned for pardoning and saving sinners.
That he might make his mighty power to be known - Exodus 9:16. Compare the notes at Romans 9:17.

He saved them for his name's sake - למען שמו lemaan shemo, "on account of his name;" to manifest his own power, goodness, and perfections. There was nothing which he could draw from them as a reason why he should save them; therefore he drew the reason from himself. There is a singular gloss in the old Psalter on this verse: "Whan thai cam oute of Egypt to the rede Se, whare thai were closed on a syde with a hylle that na man mygt passe: on another side was the rede See: behynde tham was men of Egypt foluand; and for this thai began to gruch, forgetand Gods mygt: bot than he safed tham, depertand the Se in twelfe, to ilk kynde of Isrel a passage." It seems as if this author thought there were twelve passages made through the Red Sea, that each tribe should have a passage to itself.

Nevertheless he (e) saved them for his name's sake, that he might make his mighty power to be known.
(e) The inestimable goodness of God appears in this, that he would rather change the order of nature than have his people not be delivered, even though they were wicked.

Nevertheless, he saved them for his name's sake,.... Not for any worth or worthiness in them; not for their righteousness sake, for they were a rebellious and disobedient people; but for his name's sake, because his name was called upon them, and he was called the God of the Hebrews, as Aben Ezra observes; and the God of Abraham, Isaac, and Jacob, their ancestors; to whom he had promised the land of Canaan, and was their covenant God; and because of his covenant, and of his divine perfections, and the glory of them, which were engaged to make it good; therefore he saved them, see Ezekiel 20:9. And so the spiritual Israel of God are saved, not for any superior excellencies in them, for they are in no wise better than others; nor for their righteousness sake; but to display the wisdom and faithfulness of God, his grace and mercy, his justice and holiness, power, goodness, and truth. And so here it follows;
that he might make his mighty power to be known; not only among the Israelites, but among the nations of the world; who, had he not saved them, might have thought, and said, that it was for want of power, and that he could not do it; see Deuteronomy 9:28.

for his name's sake-- (Ezekiel 20:14).

Saved them - That he may vindicate his name from the blasphemous reproaches, which would have been cast upon it, if they had been destroyed.
