And he rebuked the Red Sea, and it was dried up: and he led them through the depths, as in a wilderness.

“"He rebuked the Red Sea also, and it was dried up" [Psalm 106:9]. We do not read that any voice was sent forth from Heaven to rebuke the sea; but he has called the Divine Power by which this was effected, a rebuke: unless indeed any one may choose to say, that the sea was secretly rebuked, so that the waters might hear, and yet men could not. The power by which God acts is very abstruse and mysterious, a power which He causes that even things devoid of sense instantly obey at His will. "So He led them through the deeps, as through a wilderness." He calls a multitude of waters the deeps. For some wishing to give the sense of this whole verse, have translated, "So He led them forth amid many waters." What then does "through the deeps, as through a wilderness," mean, except that that had become as a wilderness from its dryness, where before had been the watery deeps?”

“He rebuked the Red sea also, and it was dried up,.... By sending a strong east wind, which drove the waters back, and made the sea a dry land, Exo 14:21. So he led them through the depths; that is, the deep waters of the sea, which were cast up as an heap, and stood as a wall on each side, through which they passed. As through the wilderness; or rather, "as on a plain"; for a passage through a wilderness where no roads are, and many obstructions be, is not easy; and so it is manifestly to be understood in Isa 63:13, where Jarchi and Kimchi interpret it a plain and smooth ground, a champaign country; and so the word is used for a plain, in opposition to mountains, in Jer 9:10, and then the sense is, that God led them through the sea, being dried up, as if they were led through a plain and open country, where was nothing to obstruct their march; an emblem of baptism, Co1 10:1, and of the passage of the people of God through this world; See Gill on Psa 78:13.”
