John 8:5-7

5Now in the law Moses commanded us to stone such: what then sayest thou of her?

6And this they said, tempting him, that they might have whereof to accuse him. But Jesus stooped down, and with his finger wrote on the ground.

7But 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.
