Exodus 14:8-10

8The Lord hardened the heart of Pharaoh, king of Egypt, and he pursued the Israelites, as they were leaving confidently and defiantly.

9The Egyptians chased them with all the horses and war-chariots of Pharaoh, his horsemen and his army, and they overtook them as they camped by the sea, beside Pi-hahiroth, in front of Baal-zephon.

10As 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.
