'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 the shade of them is agreeable: therefore your daughters shall be guilty of lewdness, and your spouses shall commit adultery.

I will not punish your daughters when they are guilty of lewdness, nor your spouses when they commit adultery: for they themselves are separated with prostitutes, and they sacrifice with harlots: therefore the people that doth not understand shall fall.
