'Commit Adultery' in the Bible

They sacrifice upon the tops of the mountains, and burn incense upon the hills, under oaks and poplars and elms, because its shadow is good: therefore your daughters shall commit harlotry, and your spouses shall commit adultery.

I will not punish your daughters when they commit harlotry, nor your spouses when they commit adultery: for the men themselves are gone apart with harlots, and they sacrifice with prostitutes: therefore the people that do not understand shall fall.
