Mark 3:13-19 (New International Version)

The Appointing of the Twelve Apostles

 ¹³Jesus went up on a mountainside and called to him those he wanted, and they came to him. ¹⁴He appointed twelve—designating them apostles^[a]—that they might be with him and that he might send them out to preach ¹⁵and to have authority to drive out demons. ¹⁶These are the twelve he appointed: Simon (to whom he gave the name Peter ¹⁷ James son of Zebedee and his brother John (to them he gave the name Boanerges, which means Sons of Thunder); ¹⁸Andrew, Philip, Bartholomew, Matthew, Thomas, James son of Alphaeus, Thaddaeus, Simon the Zealot ¹⁹and Judas Iscariot, who betrayed him.
