Mark 3:13-19 - The Selection Of The Twelve Apostles
13 And Jesus made his way up the hill, and called those whom he wished; and they went to him. 14 And he appointed twelve--whom he also named 'Apostles'--that they might be with him, and that he might send them out as his Messengers, to preach, 15 And with power to drive out demons.
16 So he appointed the Twelve--Peter (which was the name that Jesus gave to Simon), 17 James, the son of Zebediah, and his brother John (to whom he gave the name of Boanerges, which means the Thunderers), 18 Andrew, Philip, Bartholomew, Matthew, Thomas, James the son of Alphaeus, Thaddaeus, Simon the Zealot, 19 And Judas Iscariot, the man that betrayed him.
12 Now about that time, Jesus went out, up the hill, to pray, and spent the whole night in prayer to God. 13 When day came, he summoned his disciples, and chose twelve of them, whom he also named 'Apostles.'
14 They were Simon (whom Jesus also named Peter), and his brother Andrew, James, John, Philip, Bartholomew, 15 Matthew, Thomas, James son of Alphaeus, Simon known as the Zealot, 16 Judas son of James, and Judas Iscariot, who proved a traitor.
