'Adultery' in the Bible

And I see when (for all the causes whereby backsliding Israel committed adultery) I have sent her away, and I give the bill of her divorce unto her, that treacherous Judah her sister hath not feared, and goeth and committeth fornication -- she also.

For this I am not propitious to thee, Thy sons have forsaken Me, And are satisfied by that which is not god, I satisfy them, and they commit adultery, And at the house of a harlot They gather themselves together.

Stealing, murdering, and committing adultery, And swearing to falsehood, and giving perfume to Baal, And going after other gods whom ye knew not.

And in prophets of Jerusalem I have seen a horrible thing, Committing adultery, and walking falsely, Yea, they strengthened the hands of evil doers, So that they have not turned back Each from his wickedness, They have been to me -- all of them -- as Sodom, And its inhabitants as Gomorrah.

Because that they have done folly in Israel, and commit adultery with the wives of their neighbours, and speak a word in My name falsely that I have not commanded them, and I am He who knoweth and a witness -- an affirmation of Jehovah.
