Luke 6:12-16  (12) And it came to pass in those days, that he went out into a mountain to pray, and continued all night in prayer to God.  (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 Alphaeus, and Simon called Zelotes,  (16)  And Judas the brother of James, and Judas Iscariot, which also was the traitor.
John 15:12-15  (12) This is my commandment, That ye love one another, as I have loved you.  (13)  Greater love hath no man than this, that a man lay down his life for his friends.  (14)  Ye are my friends, if ye do whatsoever I command you.  (15)  Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you.
