John 8:5-7

5Now in the Law Moses commanded us to stone such women [to death]. So what do You say [to do with her—what is Your sentence]?”

6They 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.

7However, 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.”
