Exodus 20:14
14“You shall not commit adultery.
Proverbs 6:23–35
23For the commandment is a lamp and the teaching a light,and the reproofs of discipline are the way of life,24to preserve you from the evil woman,from the smooth tongue of the adulteress.25Do not desire her beauty in your heart,and do not let her capture you with her eyelashes;26for the price of a prostitute is only a loaf of bread,but a married woman hunts down a precious life.27Can a man carry fire next to his chestand his clothes not be burned?28Or can one walk on hot coalsand his feet not be scorched?29So is he who goes in to his neighbor’s wife;none who touches her will go unpunished.30People do not despise a thief if he stealsto satisfy his appetite when he is hungry,31but if he is caught, he will pay sevenfold;he will give all the goods of his house.32He who commits adultery lacks sense;he who does it destroys himself.33He will get wounds and dishonor,and his disgrace will not be wiped away.34For jealousy makes a man furious,and he will not spare when he takes revenge.35He will accept no compensation;he will refuse though you multiply gifts.
Matthew 5:27–28
27“You have heard that it was said, ‘You shall not commit adultery.’ 28But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.
John 8:1–11
8:1but Jesus went to the Mount of Olives. 2Early in the morning he came again to the temple. All the people came to him, and he sat down and taught them. 3The scribes and the Pharisees brought a woman who had been caught in adultery, and placing her in the midst 4they said to him, “Teacher, this woman has been caught in the act of adultery. 5Now in the Law, Moses commanded us to stone such women. So what do you say?” 6This they said to test him, that they might have some charge to bring against him. Jesus bent down and wrote with his finger on the ground. 7And 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.” 8And once more he bent down and wrote on the ground. 9But 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 him. 10Jesus stood up and said to her, “Woman, where are they? Has no one condemned you?” 11She said, “No one, Lord.” And Jesus said, “Neither do I condemn you; go, and from now on sin no more.”]]
