'Commit Adultery' in the Bible

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

but I -- I say to you, that every one who is looking on a woman to desire her, did already commit adultery with her 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.

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.'"
