John 8:4-7

they *said to Him, “Teacher, this woman has been caught in adultery, in the very act. Now in the Law Moses commanded us to stone such women; what then do You say?” They were saying this, testing Him, so that they might have grounds for accusing Him. But Jesus stooped down and with His finger wrote on the ground. But when they persisted in asking Him, He straightened up, and said to them, “He who is without sin among you, let him be the first to throw a stone at her.”
