Mark 3:13-19

Then Jesus went up on a mountain and called to him those he wanted, and they came to him. Jesus chose twelve and called them apostles. He wanted them to be with him, and he wanted to send them out to preach and to have the authority to force demons out of people. These are the twelve men he chose: Simon (Jesus named him Peter), James and John, the sons of Zebedee (Jesus named them Boanerges, which means “Sons of Thunder”), Andrew, Philip, Bartholomew, Matthew, Thomas, James the son of Alphaeus, Thaddaeus, Simon the Zealot, and Judas Iscariot, who later turned against Jesus.
