I Kings 19:13, 19

So it was, when Elijah heard it, that he wrapped his face in his mantle and went out and stood in the entrance of the cave. Suddenly a voice came to him, and said, “What are you doing here, Elijah?”

So he departed from there, and found Elisha the son of Shaphat, who was plowing with twelve yoke of oxen before him, and he was with the twelfth. Then Elijah passed by him and threw his mantle on him.
