Luke 6:12-17 ESV
In these days he went out to the mountain to pray, and all night he continued in prayer to God. And when day came, he called his disciples and chose from them twelve, whom he named apostles: Simon, whom he named Peter, and Andrew his brother, and James and John, and Philip, and Bartholomew, and Matthew, and Thomas, and James the son of Alphaeus, and Simon who was called the Zealot, and Judas the son of James, and Judas Iscariot, who became a traitor.
And he came down with them and stood on a level place, with a great crowd of his disciples and a great multitude of people from all Judea and Jerusalem and the seacoast of Tyre and Sidon
