'Adultery' in the Bible

I saw, when, for this very cause that backsliding Israel had committed adultery, I had put her away and given her a bill of divorce, yet treacherous Judah, her sister, didn't fear; but she also went and played the prostitute.

It happened through the lightness of her prostitution, that the land was polluted, and she committed adultery with stones and with stocks.

"How can I pardon you? Your children have forsaken me, and sworn by what are no gods. When I had fed them to the full, they committed adultery, and assembled themselves in troops at the prostitutes' houses.

Will you steal, murder, and commit adultery, and swear falsely, and burn incense to Baal, and walk after other gods that you have not known,

In the prophets of Jerusalem also I have seen a horrible thing: they commit adultery, and walk in lies; and they strengthen the hands of evildoers, so that none does return from his wickedness: they are all of them become to me as Sodom, and its inhabitants as Gomorrah.

because they have worked folly in Israel, and have committed adultery with their neighbors' wives, and have spoken words in my name falsely, which I didn't command them; and I am he who knows, and am witness, says Yahweh.
