1 Kings 7:14; 1 Kings 19:19

14 He was a widow's son from the tribe of Naphtali, and his father was a man of Tyre, a worker in bronze; and he was filled with wisdom and understanding and skill for doing any work in bronze. So he came to King Solomon and performed all his work.
19 So he departed from there and found Elisha the son of Shaphat, while he was plowing with twelve pairs of oxen before him, and he with the twelfth . And Elijah passed over to him and threw his mantle on him.
