To him which divided the Red sea into parts - More literally, "Parted it into parts;" made parts of that which before was unbroken and a whole. It was actually divided into two parts, so that the Hebrews passed between them: Exodus 14:21-22.

For his mercy ... - This, too, was an exercise of mercy, or a manifestation of benevolence toward them and toward the world, to be measured by all the good which would result from it in itself, and by all the power which was put forth to effect it.

Divided the Red Sea into parts - Some of the Jews have imagined that God made twelve paths through the Red Sea, that each tribe might have a distinct passage. Many of the fathers were of the same opinion; but is this very likely?

To him which divided the Red sea into parts,.... Into two parts, so that the waters of it stood as a wall on the right and left hand of the Israelites, as they passed through; this was done by means of a strong east wind, Exodus 14:21. The Jews have a tradition, which Jarchi, Kimchi, and Arama, make mention of, that the sea was divided into twelve parts, according to the twelve tribes of Israel, and every tribe had a path by itself to walk in; but for this there is no foundation: however, the dividing it into parts was a wonderful work, and a rich display of mercy to Israel;

for his mercy endureth for ever; the children of Israel were encompassed about, and in the utmost distress: the rocks were on each side, Pharaoh and his host behind them, the Red sea before them; and so no visible way of escape; but the Lord cut a way for them through the sea, and saved them. The sea is an emblem of this world, which is like a tempestuous troubled sea; where everything is restless, fluctuating, and passing away; where the people of God are tossed with tempests; and where afflictions, like the waves and billows of the sea, come over them one after another; and through which they must pass and enter the kingdom: and God, that wills, orders, and appoints them, sets these proud waves of the sea their bounds, or makes them a calm; and, sooner or later, makes a way through them and out of them, which is owing to his enduring mercy, 1 Corinthians 10:13.

To him which divided the Red sea into parts: for his mercy endureth for ever:

136:10-22 The great things God did for Israel, when he brought them out of Egypt, were mercies which endured long to them; and our redemption by Christ, which was typified thereby, endures for ever. It is good to enter into the history of God's favours, and in each to observe, and own, that his mercy endureth for ever. He put them in possession of a good land; it was a figure of the mercy of our Lord Jesus Christ.
