John 8:4-7

They said to Jesus, “Teacher, this woman was caught having sexual relations with a man who is not her husband. The law of Moses commands that we stone to death every woman who does this. What do you say we should do?” They were asking this to trick Jesus so that they could have some charge against him. But Jesus bent over and started writing on the ground with his finger. When they continued to ask Jesus their question, he raised up and said, “Anyone here who has never sinned can throw the first stone at her.”
