Adam Clarke on Job 26:12

He divideth the sea with his power - Here is a manifest allusion to the passage of the Red Sea by the Israelites, and the overthrow of Pharaoh and his host, according to the opinion of the most eminent critics.

He smiteth through the proud - רהב Rahab, the very name by which Egypt is called Isa 51:9, and elsewhere. Calmet remarks: "This appears to refer only to the passage of the Red Sea, and the destruction of Pharaoh. Were we not prepossessed with the opinion that Job died before Moses, every person at the first view of the subject must consider it in this light." I am not thus prepossessed. Let Job live when he might, I am satisfied the Book of Job was written long after the death of Moses, and not earlier than the days of Solomon, if not later. The farther I go in the work, the more this conviction is deepened; and the opposite sentiment appears to be perfectly gratuitous.
