I Kings 19:16-19

Also you shall anoint Jehu the son of Nimshi as king over Israel. And Elisha the son of Shaphat of Abel Meholah you shall anoint as prophet in your place. It shall be that whoever escapes the sword of Hazael, Jehu will kill; and whoever escapes the sword of Jehu, Elisha will kill. Yet I have reserved seven thousand in Israel, all whose knees have not bowed to Baal, and every mouth that has not kissed him.” 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.
