Mark 3:13-19

13 He climbed a mountain and invited those he wanted with him. They climbed together.

14 He settled on twelve, and designated them apostles. The plan was that they would be with him, and he would send them out to proclaim the Word

15 and give them authority to banish demons.

16 These are the Twelve: Simon (Jesus later named him Peter, meaning "Rock"),

17 James, son of Zebedee, John, brother of James (Jesus nicknamed the Zebedee brothers Boanerges, meaning "Sons of Thunder"),

18 Andrew, Philip, Bartholomew, Matthew, Thomas, James, son of Alphaeus, Thaddaeus, Simon the Canaanite,

19 Judas Iscariot (who betrayed him).
