When they kept on questioning him, he straightened up and said to them, “If any one of you is without sin, let him be the first to throw a stone at her.”
“Under the law (Deut 17:7) the witnesses were to cast the first stone. Jesus maintained and vindicated the law, but imposed a condition which they had overlooked. The one who executed the law must be free from the same crime, lest by stoning the woman he condemn himself as worthy of a like death. There is no doubt that the words of Jesus impressed upon them the truth that freedom from the outward act did not imply inward purity or sinlessness (Mat 5:27,28).” (TFG 452) We should also take this to heart. Before finding fault with others, we would do well to first examine ourselves and then realize that we don’t have the right to point fingers because we, too, are guilty of sin. We are to restore the sinner and not condemn them.
Deut 17:7 The hands of the witnesses must be the first in putting him to death, and then the hands of all the people. You must purge the evil from among you.
Mat 5:27-28 “You have heard that it was said, ‘Do not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.
