Θωμᾶς saith unto him, Lord, we know not whither thou goest; and how can we know the way?
But Θωμᾶς, one of the twelve, called Didymus, was not with them when Jesus came.
And after eight days again his disciples were within, and Θωμᾶς with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you.
Then saith he to Θωμᾶς, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing.
And Θωμᾶς answered and said unto him, My Lord and my God.
Jesus saith unto him, Θωμᾶς, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.
There were together Simon Peter, and Θωμᾶς called Didymus, and Nathanael of Cana in Galilee, and the sons of Zebedee, and two other of his disciples.
And when they were come in, they went up into an upper room, where abode both Peter, and James, and John, and Andrew, Philip, and Θωμᾶς, Bartholomew, and Matthew, James the son of Alphaeus, and Simon Zelotes, and Judas the brother of James.
