John 8:5-7
8:5 In the law Moses commanded us to stone to death such women. What then do you say?”
8:6 (Now they were asking this in an attempt to trap him, so that they could bring charges against him.) Jesus bent down and wrote on the ground with his finger.
8:7 When they persisted in asking him, he stood up straight and replied, “Whoever among you is guiltless may be the first to throw a stone at her.”
