Luke 6:12-16

One of those days
Jesus went out to a mountainside to pray,
and spent the night praying to God.
When morning came,
He called His disciples to Him
and chose twelve of them,
whom he also designated apostles:
Simon (whom He named Peter),
his brother Andrew,
James,
John,
Philip,
Bartholomew,
Matthew,
Thomas,
James son of Alphaeus,
Simon who was called the Zealot,
Judas son of James,
and Judas Iscariot, who became a traitor.
