One of those days Jesus went out to a mountainside to pray, and spent the night praying to God. 13 When morning came, he called his disciples to him and chose twelve of them, whom he also designated apostles: 14 Simon (whom he named Peter), his brother Andrew, James, John, Philip, Bartholomew, 15 Matthew, Thomas, James son of Alphaeus, Simon who was called the Zealot, 16 Judas son of James, and Judas Iscariot, who became a traitor.
Luke 6:12-16 NIV
Jesus called his twelve disciples to him and gave them authority to drive out impure spirits and to heal every disease and sickness. . . . 5These twelve Jesus sent out with the following instructions: 8 Heal the sick, raise the dead, cleanse those who have leprosy, drive out demons. Freely you have received; freely give.
Matthew 10:1, 5a, 8 NIV
