Exodus 14:4, 10, 31

I will harden (make stubborn, defiant) Pharaoh’s heart, so that he will pursue them; and I will be glorified and honored through Pharaoh and all his army, and the Egyptians shall know [without any doubt] and acknowledge that I am the LORD.” And they did so.

As Pharaoh approached, the Israelites looked up and saw the Egyptians marching after them, and they were very frightened; so the Israelites cried out to the LORD.

When Israel saw the great power which the LORD had used against the Egyptians, they feared the LORD [with reverence and awe-filled respect], and they believed in the LORD, and in His servant Moses.
