Gospel according to Saint Mark 3:13-19
Jesus went up the mountain and summoned those whom he wanted and they came to him. He appointed twelve [whom he also named apostles] that they might be with him and he might send them forth to preach and to have authority to drive out demons:[he appointed the twelve:] Simon, whom he named Peter; James, son of Zebedee, and John the brother of James, whom he named Boanerges, that is, sons of thunder; Andrew, Philip, Bartholomew, Matthew, Thomas, James the son of Alphaeus; Thaddeus, Simon the Cananean, and Judas Iscariot who betrayed him.
