Exodus 14:29–31

29 But the Israelites had walked through the sea on dry ground, with the waters like a wall to them on their right and their left. 30 That day the Lord saved Israel from the power of the Egyptians, and Israel saw the Egyptians dead on the seashore. 31 When Israel saw the great power that the Lord used against the Egyptians, the people feared the Lord and believedk in him and in his servant Moses.
