And he made ready his chariot, and took his people with him:
And he took six hundred chosen chariots, and all the chariots of Egypt, and captains over every one of them.
And the Lord hardened the heart of Pharaoh king of Egypt, and he pursued after the children of Israel: and the children of Israel went out with an high hand.
But the Egyptians pursued after them, all the horses and chariots of Pharaoh, and his horsemen, and his army, and overtook them encamping by the sea, beside Pi–hahiroth, before Baal–zephon.
And when Pharaoh drew nigh, the children of Israel lifted up their eyes, and, behold, the Egyptians marched after them; and they were sore afraid: and the children of Israel cried out unto the Lord.
