In context
13Then Jesus went up on the mountain and called for those He wanted, and they came to Him. 14He appointed twelve of them, whom He designated as apostles, to accompany Him, to be sent out to preach, 15and to have authority to drive out demons. 16These are the twelve He appointed: Simon (whom He named Peter), 17James son of Zebedee and his brother John (whom He named Boanerges, meaning “Sons of Thunder”), 18Andrew, Philip, Bartholomew, Matthew, Thomas, James son of Alphaeus, Thaddaeus, Simon the Zealot, 19and Judas Iscariot, who betrayed Jesus.
