1 Kings 19:12-21

and after the earthquake a fire; but Jehovah was not in the fire: and after the fire a still small voice. And 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 unto him, and said, What doest thou here, Elijah? And he said, I have been very jealous for Jehovah, the God of hosts; for the children of Israel have forsaken thy covenant, thrown down thine altars, and slain thy prophets with the sword; and I, even I only, am left; and they seek my life, to take it away. And Jehovah said unto him, Go, return on thy way to the wilderness of Damascus: and when thou comest, thou shalt anoint Hazael to be king over Syria; and Jehu the son of Nimshi shalt thou anoint to be king over Israel; and Elisha the son of Shaphat of Abel-meholah shalt thou anoint to be prophet in thy room. And it shall come to pass, that him that escapeth from the sword of Hazael shall Jehu slay; and him that escapeth from the sword of Jehu shall Elisha slay. Yet will I leave me seven thousand in Israel, all the knees which have not bowed unto Baal, and every mouth which hath not kissed him. 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 over unto him, and cast his mantle upon him. And he left the oxen, and ran after Elijah, and said, Let me, I pray thee, kiss my father and my mother, and then I will follow thee. And he said unto him, Go back again; for what have I done to thee? And he returned from following him, and took the yoke of oxen, and slew them, and boiled their flesh with the instruments of the oxen, and gave unto the people, and they did eat. Then he arose, and went after Elijah, and ministered unto him.
