Jesus went up into the hills and summoned those he wanted. So they came to him and he appointed twelve; they were to be his companions and to be sent out to preach, with power to cast out devils. And so he appointed the Twelve: Simon to whom he gave the name Peter, James the son of Zebedee and John the brother of James, to whom he gave the name Boanerges or ‘Sons of Thunder’; then Andrew, Philip, Bartholomew, Matthew, Thomas, James the son of Alphaeus, Thaddaeus, Simon the Zealot and Judas Iscariot, the man who was to betray him.
