Joshua 24:6-7

6When I brought your ancestors out of Egypt, they reached the Red Sea. The Egyptians chased after them to the sea, with soldiers on horses and in chariots.

7But your ancestors called to the Lord for help. He made the space between them and the Egyptians become dark. He caused the Egyptian soldiers to drown in the sea. Your ancestors saw what I did to the Egyptians with their own eyes. After that, they lived in the desert for a long time.
