John 8:7-9

7 So when they continued asking him, he lifted himself up and said unto them, He that is without sin among you, let him [be] the first to cast a stone at her.

8 And again he stooped down and wrote on the ground.

9 And those who heard [it], being convicted by [their own] conscience, went out one by one, beginning at the eldest [even] unto the last; and Jesus was left alone and the woman that had been in the midst.
