'Adultery' in the Bible

And I saw that when for all the causes wherein backsliding Israel committed adultery I had put her away, and given her a bill of divorce, yet the treacherous Judah, her sister, feared not, but went and committed fornication also.

And it came to pass through the lightness of her fornication that she polluted the land, and committed adultery with stones and with stocks.

Wherefore should I pardon thee? Thy children have forsaken me, and swear by them that are not God. I have satiated them, and they have committed adultery, and they troop to the harlots' house.

What? steal, murder, and commit adultery, and swear falsely, and burn incense unto Baal, and walk after other gods whom ye know not ...

And in the prophets of Jerusalem have I seen a horrible thing: they commit adultery, and walk in falsehood, and strengthen the hands of evildoers, so that none doth return from his wickedness. They are all become unto me as Sodom, and the inhabitants thereof as Gomorrah.

because they have committed infamy in Israel, and have committed adultery with their neighbours' wives, and have spoken words of falsehood in my name, which I had not commanded them: and I am he that knoweth, and am witness, saith Jehovah.
