John 11:16; John 20:24; John 21:2

16 Then said Thomas, which is called Didymus, unto his fellowdisciples, Let us also go, that we may die with him.

24 But Thomas, one of the twelve, called Didymus, was not with them when Jesus came.

2 There were together Simon Peter, and Thomas called Didymus, and Nathanael of Cana in Galilee, and the sons of Zebedee, and two other of his disciples.
