John 8
3 The scribes and the Pharisees brought a woman taken in adultery. Having set her in the midst,
4 they told him, "Teacher, we found this woman in adultery, in the very act.
5 Ref Now in our law, Moses commanded us to stone such. What then do you say about her?"
6 Ref They said this testing him, that they might have something to accuse him of. But Jesus stooped down, and wrote on the ground with his finger.
7 Ref But when they continued asking him, he looked up and said to them, "He who is without sin among you, let him throw the first stone at her."
8 Again he stooped down, and with his finger wrote on the ground.
