'Commit Adultery' in the Bible

They sacrifice upon the tops of the mountains, and burn incense upon the hills, under oaks and poplars and terebinths, because the shadow thereof is good: therefore your daughters play the harlot, and your brides commit adultery.

I will not punish your daughters when they play the harlot, nor your brides when they commit adultery; for the men themselves go apart with harlots, and they sacrifice with the prostitutes; and the people that doth not understand shall be overthrown.
