(13) And when it was day, he called unto him his disciples and of them he chose twelve, whom also he named apostles; (14) Simon, (whom he also named Peter), and Andrew his brother, James and John, Philip and Bartholomew, (15) Matthew and Thomas; James the son of Alpheus, and Simon called Zelotes; (16) And Judas the brother of James, and Judas Iscariot, which also was the traitor.
Christ's call of his Apostles we have noticed, Matthew 10:1. and again Mark 3:14. See Matthew 10:1, etc. and my Poor Man's Concordance, on the subject.
