1 Kings 19:19; 1 Kings 19:21

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.

21 So he returned from following him, and took the pair of oxen and sacrificed them and boiled their flesh with the implements of the oxen, and gave it to the people and they ate. Then he arose and followed Elijah and ministered to him.
