Matthew 5:27

Thou shalt not commit adultery.

And the man that committeth adultery with another man's wife, even he that committeth adultery with his neighbor's wife, the adulterer and the adulteress shall surely be put to death.

Neither shalt thou commit adultery.

If a man be found lying with a woman married to an husband, then they shall both of them die, both the man that lay with the woman, and the woman: so shalt thou put away evil from Israel. If a damsel that is a virgin be betrothed unto an husband, and a man find her in the city, and lie with her; Then ye shall bring them both out unto the gate of that city, and ye shall stone them with stones that they die; the damsel, because she cried not, being in the city; and the man, because he hath humbled his neighbor's wife: so thou shalt put away evil from among you.

But whoso committeth adultery with a woman lacketh understanding: he that doeth it destroyeth his own soul.
