"And as they continued to ask him, he stood up and said to them, 'Let him who is without sin among you be the first to throw a stone at her.' And once more he bent down and wrote on the ground. But when they heard it, they went away one by one, beginning with the older ones, and Jesus was left alone with the woman standing before." - John 8:7-9
While the above occasion was meant to challenge the credibility of our Lord's teaching, it opened a door of unexpected revelation. When presented with a heart searching question that cut to motive, the accusers slowly backed away, but who responded first? "...they went away one by one, beginning with the older ones" In this case, greater age brought greater wisdom.
