Verse 10. - Art thou not it which hath dried the sea? rather, was it not thou that didst dry up the sea? (comp. Exodus 14:21, 22). The waters of the Red Sea are called those of "the great deep," because they are a portion of the circumambient ocean, not a tideless land-locked basin, like the Mediterranean. That hath made; rather, that madest. The allusion is to the single occasion of the passage of the Red Sea by the Israelites. Ver. 11. - The redeemed of the Lord (see the comment on Isaiah 35:10. where the same passage occurs with scarcely any variation). Isaiah is not averse to repetitions (see Isaiah 5:25; Isaiah 9:12, 17, 21; Isaiah 10:4; Isaiah 11:1; Isaiah 65:25; Isaiah 48:22; 57:21, etc.).

51:9-16 The people whom Christ has redeemed with his blood, as well as by his power, will obtain joyful deliverance from every enemy. He that designs such joy for us at last, will he not work such deliverance in the mean time, as our cases require? In this world of changes, it is a short step from joy to sorrow, but in that world, sorrow shall never come in view. They prayed for the display of God's power; he answers them with consolations of his grace. Did we dread to sin against God, we should not fear the frowns of men. Happy is the man that fears God always. And Christ's church shall enjoy security by the power and providence of the Almighty.Art thou not it which hath dried the sea, the waters of the great deep,.... That is, the Red sea, and the deep waters of it; as it did, by causing a strong east wind to blow, which drove the sea back, and made it a dry land, in the midst of which the children of Israel walked as on dry land, Exodus 14:21 and the same arm and mighty power can and will dry up the waters of the river Euphrates, to prepare the way of the kings of the east, Revelation 16:12,

that hath made the depths of the sea a way for the ransomed to pass over? divided the waters of the sea, made a path through them for the Israelites that were redeemed out of Egyptian bondage and slavery, to pass over, and so to go to Canaan's land.
