Exodus 14:13-16, 26-27

And Moses said unto the people, Fear ye not, stand still, and see the salvation of Jehovah, which he will work for you to-day: for the Egyptians whom ye have seen to-day, ye shall see them again no more for ever. Jehovah will fight for you, and ye shall hold your peace. And Jehovah said unto Moses, Wherefore criest thou unto me? speak unto the children of Israel, that they go forward. And lift thou up thy rod, and stretch out thy hand over the sea, and divide it: and the children of Israel shall go into the midst of the sea on dry ground.

And Jehovah said unto Moses, Stretch out thy hand over the sea, that the waters may come again upon the Egyptians, upon their chariots, and upon their horsemen. And Moses stretched forth his hand over the sea, and the sea returned to its strength when the morning appeared; and the Egyptians fled against it; and Jehovah overthrew the Egyptians in the midst of the sea.
