Twin, one of the twelve (Matthew 10:3; Mark 3:18 , etc.). He was also called Didymus (John 11:16; 20:24 ), which is the Greek equivalent of the Hebrew name. All we know regarding him is recorded in the fourth Gospel (John 11:15,16; 14:4,5; 20:24,25,26-29 ). From the circumstance that in the lists of the apostles he is always mentioned along with Matthew, who was the son of Alphaeus (Mark 3:18 ), and that these two are always followed by James, who was also the son of Alphaeus, it has been supposed that these three, Matthew, Thomas, and James, were brothers.
