Exodus 14:5-9

When word reached the king of Egypt that the Israelites had fled, Pharaoh and his officials changed their minds. “What have we done, letting all those Israelite slaves get away?” they asked. So Pharaoh harnessed his chariot and called up his troops. He took with him 600 of Egypt’s best chariots, along with the rest of the chariots of Egypt, each with its commander. The LORD hardened the heart of Pharaoh, the king of Egypt, so he chased after the people of Israel, who had left with fists raised in defiance. The Egyptians chased after them with all the forces in Pharaoh’s army—all his horses and chariots, his charioteers, and his troops. The Egyptians caught up with the people of Israel as they were camped beside the shore near Pi-hahiroth, across from Baal-zephon.
