2 Kings 2:13-14

13He also took up the coat of Elijah that had fallen from him, and he went back and stood by the bank of the Jordan. 14Then he took the coat of Elijah that had fallen from him and struck the waters, and said, “Where is the Lord, the God of Elijah?” And when he also had 1struck the waters, they were divided here and there; and Elisha crossed over.
