Luke 6:12-16

12And it came to pass in those days, that he went out into a mountain to pray, and continued all night in prayer to God.

13And when it was day, he called unto him his disciples: and of them he chose twelve, whom also he named apostles; 14Simon, (whom he also named Peter,) and Andrew his brother, James and John, Philip and Bartholomew, 15Matthew and Thomas, James the son of Alphæus, and Simon called Zelotes, 16And Judas the brother of James, and Judas Iscariot, which also was the traitor.
