'Mantle of Elijah' in the Bible

He took up also the mantle of Elijah that fell from him, and went back, and stood by the bank of Jordan;

And he took the mantle of Elijah that fell from him, and struck the waters, and said, Where is the LORD God of Elijah? and when he also had struck the waters, they parted to the one side and to the other: and Elisha went over.
