What Did Jesus Say About Adultery?

You have heard that it was said by them of old time, you shall not commit adultery:

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

And if your right eye offends, you pluck it out, and cast it from you: for it is profitable for you that one of your members should perish, and not that your whole body should be cast into hell.

And if your right hand offends you, cut it off, and cast it from you: for it is profitable for you that one of your members should perish, and not that your whole body should be cast into hell.

It has been said; Whosoever shall put away his wife, let him give her writing of divorce: But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causes her to commit adultery: and whosoever shall marry her that is divorced commits adultery. Matthew 5 vs 27-32.
