John 8:6-9

6This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not.

7So 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.

8And again he stooped down, and wrote on the ground.

9And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst.
