2 Kings 2:13-14

13And he took up the cloak of Elijah that had fallen from him and went back and stood on the bank of the Jordan.

14Then he took the cloak of Elijah that had fallen from him and struck the water, saying, "Where is the Lord, the God of Elijah?" And when he had struck the water, the water was parted to the one side and to the other, and Elisha went over.
