The only one qualified to throw a stone . . . didn’t.

From John 8:4-7:  “They said to Him, ‘Teacher, this woman was caught in the very act of committing adultery.  Now in the law Moses commanded us to stone such women.  Now what do You say?’  They said this to test Him, so that they might have some charge to bring against Him.  Jesus bent down and wrote with His finger on the ground.  When they kept on questioning Him, He straightened up and said to them, ‘Let anyone among you who is without sin be the first to throw a stone at her.'”
