Thou didst blow with thy wind,.... A strong east wind, Exo 14:22 which is the Lord Christ's, who has it in his treasury, holds it in his fists, sends it out as he pleases, and it fulfils his word and will: the sea covered them; which stood up in an heap as a wall to let Israel pass through, and fell down with all its waves and billows with great force upon the Egyptians, and covered and drowned them: they sunk as lead in the mighty waters; which is a very heavy metal, and, being cast into the water, sinks to the bottom at once, as did the Egyptians in the Red sea, and as Babylon the great will, and never rise more, Rev 18:21.
