JOS 24:7

7 Then [your ancestors] pleaded with me to help them. So he caused ◄darkness/a very dark cloud► to come between your ancestors and the Egyptian army, so that the Egyptian army could not see your ancestors. I separated the water in the Red Sea so that your ancestors could cross it, but when the Egyptian army tried to cross in the same way to pursue them, I caused the water to come back and cover them, and the Egyptian soldiers all drowned, as your ancestors watched and were amazed [IDM]. But after that, you lived in the desert for many years.
