2 Kings 2:13-14

13He picked up Elijah's coat that had fallen off. He went and he stood on the shore of the Jordan River.

14He took Elijah's coat and he hit the water with it. He said, ‘Now is the Lord, Elijah's God, with me?’ When he hit the water with Elijah's coat, the water became separate, to the left side and to the right side. Elisha went across the river.
