1 Kings 19:13-14

13And it was so, when Elijah heard it, that he wrapped his face in his mantle, and went out, and stood in the entrance of the cave. And, behold, there came a voice to him, and said, What doest thou here, Elijah? 14And he said, I have been very jealous for the LORD God of hosts: because the children of Israel have forsaken thy covenant, thrown down thy altars, and slain thy prophets with the sword; and I, I only, am left; and they seek my life, to take it away.
