Mark 3:13-19

13He went up on the hillside and called those whom He Himself wanted and chose; and they came to Him.

14And He appointed twelve [disciples], so that they would be with Him [for instruction] and so that He could send them out to preach [the gospel as apostles—that is, as His special messengers, personally chosen representatives],

15and to have authority and power to cast out demons.

16He appointed the twelve: Simon (to whom He gave the name Peter),

17and James, the son of Zebedee, and John the brother of James (to them He gave the name Boanerges, that is, “Sons of Thunder”);

18and [He also appointed] Andrew, and Philip, and Bartholomew (Nathanael), and Matthew (Levi the tax collector), and Thomas, and James the son of Alphaeus, and Thaddaeus (Judas the son of James), and Simon the Zealot;

19and Judas Iscariot, who betrayed Him.
