Exodus 14:13-16; Exodus 14:21-22

13 Moses answered, "Don't be afraid! Stand your ground, and you will see what the Lord will do to save you today; you will never see these Egyptians again. 14 The Lord will fight for you, and all you have to do is keep still." 15 The Lord said to Moses, "Why are you crying out for help? Tell the people to move forward. 16 Lift up your walking stick and hold it out over the sea. The water will divide, and the Israelites will be able to walk through the sea on dry ground.
21 Moses held out his hand over the sea, and the Lord drove the sea back with a strong east wind. It blew all night and turned the sea into dry land. The water was divided, 22 and the Israelites went through the sea on dry ground, with walls of water on both sides.
