John 20:24-26

24Now Thomas (also known as Didymus), one of the Twelve, was not with the disciples when Jesus came.

25So the other disciples told him, “We have seen the Lord!” But he said to them, “Unless I see the nail marks in his hands and put my finger where the nails were, and put my hand into his side, I will not believe.”

26A week later his disciples were in the house again, and Thomas was with them. Though the doors were locked, Jesus came and stood among them and said, “Peace be with you!”
