And the Egyptians shall know that I am the Lord,.... Acknowledge him to be Jehovah, the self-existent, eternal, and immutable Being, the one only living and true God, who is wise and powerful, faithful, just, and true; that is, those Egyptians that were left behind in Egypt, hearing what was done at the Red sea; for as for those that came with Pharaoh, they all perished to a man: when I have gotten me honour upon Pharaoh, upon his chariots, and upon his horsemen; by casting them into the sea, and drowning them there, thereby showing himself to be mightier than he.
