John 8:7-9

However, when they persisted in questioning Him, He straightened up and said, “He who is without [any] sin among you, let him be the first to throw a stone at her.” [Deut 17:7] Then He stooped down again and started writing on the ground. They listened [to His reply], and they began to go out one by one, starting with the oldest ones, until He was left alone, with the woman [standing there before Him] in the center of the court.
