'Commit Adultery' in the Bible

On the headlands of the mountains, they sacrifice, and, on the hills, burn they incense, under oak and poplar and terebinth, because, pleasant, is the shade thereof: For this cause, do your daughters, become unchaste, and, your brides, commit adultery.

I do not bring punishment upon your daughters when they become unchaste, nor upon your brides, when they commit adultery, for, the men themselves, with unchaste women, do seclude themselves, and, with the common women of the shrine, do offer sacrifice, - and, a people who will not discern, must be ruined.
