'Adultery' in the Bible

Ye have heard that it was said by them of old time, Thou shalt not commit adultery:

But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.

But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.

It is out of the heart that evil thoughts come, as well as murder, adultery, sexual immorality, stealing, false testimony, and slander.

And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.

He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness,

Jesus said, ""You must not murder, you must not commit adultery, you must not steal, you must not give false testimony, honor your father and mother,' and, "you must love your neighbor as yourself.'"
