1 Kings 19:16-19

16and Jehu the son of Nimshi shalt thou anoint king over Israel; and Elisha the son of Shaphat of Abel-meholah shalt thou anoint prophet in thy stead.

17And it shall come to pass, [that] him that escapeth the sword of Hazael shall Jehu slay; and him that escapeth the sword of Jehu shall Elisha slay.

18Yet I have left [myself] seven thousand in Israel, all the knees that have not bowed unto Baal, and every mouth that hath not kissed him.

19And he departed thence, and found Elisha the son of Shaphat, who was ploughing [with] twelve yokes before him, and he with the twelfth; and Elijah went over to him, and cast his mantle on him.
