Exodus 17-19

15 And Moses built an altar and called its name, The-LORD-Is-My-Banner;

The Banner declares identity, and in that identity is the intended victory.

11 Now I know that the LORD is greater than all the gods; for in the very thing in which they behaved proudly, He was above them.

C'mon! Egypt displayed its ability to curse and threaten, but the bully got his comeuppance!
