Exodus 14:24-27
24
It happened in the morning watch, that Yahweh looked out on the Egyptian army through the pillar of fire and of cloud, and confused the Egyptian army.
25
He took off their chariot wheels, and they drove them heavily; so that the Egyptians said, "Let's flee from the face of Israel, for Yahweh fights for them against the Egyptians!"
26
Yahweh said to Moses, "Stretch out your hand over the sea, that the waters may come again on the Egyptians, on their chariots, and on their horsemen."
27
Moses stretched out his hand over the sea, and the sea returned to its strength when the morning appeared; and the Egyptians fled against it. Yahweh overthrew the Egyptians in the midst of the sea.
