John 20:23 YLT

²¹  Jesus, therefore, said to them again, 'Peace to you; according as the Father hath sent me, I also send you;'

²²  and this having said, he breathed on 'them', and saith to them, 'Receive the Holy Spirit;

²³  if of any ye may loose the sins, they are loosed to them; if of any ye may retain, they have been retained.'

²⁴  And Thomas, one of the twelve, who is called Didymus, was not with them when Jesus came;

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