“So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.”
King James Version (KJV)
8:7 He that is without sin - He that is not guilty: his own conscience being the judge) either of the same sin, or of some nearly resembling it; let him - as a witness, cast the first stone at her.
Joh 8:7-9 He that is without sin among you. When they persisted, saying, "What sayest thou"? he said what was an awful rebuke. They knew that he knew their lives, that they were as guilty as the woman they had brought. They forgot the demand of Moses that the witnesses should cast the first stone (De 17:5-7), and his answer was like a bolt of lightning. Covered with shame, when he stooped and wrote again, they "went out one by one".
