1 Kings 19:13, 19

And it was so, when Elijah heard it, that he wrapped his face in his mantle, and went out, and stood in the entering in of the cave. And, behold, there came a voice unto him, and said, What doest thou here, Elijah?

So he departed thence, and found Elisha the son of Shaphat, who was plowing with twelve yoke of oxen before him, and he with the twelfth: and Elijah passed by him, and cast his mantle upon him.
