Exodus 14:5-9

When the king of Egypt was told that the Israelites had left, he and his officers changed their minds about them. They said, “What have we done? We have let the Israelites leave. We have lost our slaves!” So the king prepared his war chariot and took his army with him. He took six hundred of his best chariots, together with all the other chariots of Egypt, each with an officer in it. The LORD made the king of Egypt stubborn, so he chased the Israelites, who were leaving victoriously. The Egyptians—with all the king’s horses, chariot drivers, and army—chased the Israelites. They caught up with them while they were camped by the Red Sea, near Pi Hahiroth and Baal Zephon.
