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 John 11:16 ; John 14:4 John 14:5 ; John 20:24 John 20:25 John 20:26-29 ). 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.
