John 20:25-27

25The other disciples therefore said to him, We have seen the Lord. But he said to them, Unless I see in his hands the mark of the nails, and put my finger into the mark of the nails, and put my hand into his side, I will not believe.

26And eight days after, his disciples were again within, and Thomas with them. Jesus comes, the doors being shut, and stood in the midst and said, Peace [be] to you.

27Then he says to Thomas, Bring thy finger here and see my hands; and bring thy hand and put it into my side; and be not unbelieving, but believing.
