John 8:4-7

they said to Him, “Teacher, this woman was caught in adultery, in the very act. Now Moses, in the law, commanded us that such should be stoned. But what do You say?” This they said, testing Him, that they might have something of which to accuse Him. But Jesus stooped down and wrote on the ground with His finger, as though He did not hear. So when they continued asking Him, He raised Himself up and said to them, “He who is without sin among you, let him throw a stone at her first.”
