Exodus 14:13-16

13And Moses said to the people, Fear 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 be still.

15And Jehovah said to Moses, Why dost thou cry unto me? Speak unto the children of Israel, that they go forward.

16And thou, lift thy staff, and stretch out thy hand over the sea, and divide it; and the children of Israel shall go on dry [ground] through the midst of the sea.
