Exodus 14:13-16

13Then Moses said to the people, “Do not be afraid! Take your stand [be firm and confident and undismayed] and see the salvation of the Lord which He will accomplish for you today; for those Egyptians whom you have seen today, you will never see again.

14The Lord will fight for you while you [only need to] keep silent and remain calm.”

15The Lord said to Moses, “Why do you cry to Me? Tell the sons of Israel to move forward [toward the sea].

16As for you, lift up your staff and stretch out your hand over the sea and divide it, so that the sons of Israel may go through the middle of the sea on dry land.
