Exodus 14:4

14:4 I will harden Pharaoh’s heart, and he will chase after them. I will gain honor because of Pharaoh and because of all his army, and the Egyptians will know that I am the Lord.” So this is what they did.

Exodus 14:18

14:18 And the Egyptians will know that I am the Lord when I have gained my honor because of Pharaoh, his chariots, and his horsemen.”
