1 Kings 19:16-19

Also, anoint Jehu son of Nimshi king over Israel, and anoint Elisha son of Shaphat from Abel Meholah to succeed you as prophet. Jehu will put to death any who escape the sword of Hazael, and Elisha will put to death any who escape the sword of Jehu. Yet I reserve seven thousand in Israel—all whose knees have not bowed down to Baal and whose mouths have not kissed him.” So Elijah went from there and found Elisha son of Shaphat. He was plowing with twelve yoke of oxen, and he himself was driving the twelfth pair. Elijah went up to him and threw his cloak around him.
