John 20:24-26

But Thomas, sometimes called the Twin, one of the Twelve, was not with them when Jesus came. The other disciples told him, “We saw the Master.” But he said, “Unless I see the nail holes in his hands, put my finger in the nail holes, and stick my hand in his side, I won’t believe it.” Eight days later, his disciples were again in the room. This time Thomas was with them. Jesus came through the locked doors, stood among them, and said, “Peace to you.”
