John 8:6-9

They said this to test Him, hoping that they would have grounds for accusing Him. But Jesus stooped down and began writing on the ground with His finger. 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.
