2 Kings 2:14

And he took the mantle of Elijah that fell from him, and smote the waters, and said, Where is the Lord God of Elijah? This was not a question of doubt, but meant to say: "Thou, God of Elijah, if Thou art also mine, and if I am Thy servant according to Thy will and command as he was, then let this become evident by granting that that may take place at my word which Thou grantedst should come to pass at his. " (Menken.) And when he also had smitten the waters, they parted hither and thither; and Elisha went over. Thus Elisha received his credentials as the successor of Elijah and could go forth to carry on his prophetic work.
