Exodus 14:13-16

13And 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. 14Jehovah will fight for you, and ye shall hold your peace.

15And Jehovah said unto Moses, Wherefore criest thou unto me? speak unto the children of Israel, that they go forward. 16And 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.
