'Daughters in law' in the Bible

They sacrifice on the mountaintops,and they burn offerings on the hills,and under oaks, poplars, and terebinths,because their shade is pleasant.And so your daughters act promiscuouslyand your daughters-in-law commit adultery.

I will not punish your daughterswhen they act promiscuouslyor your daughters-in-lawwhen they commit adultery,for the men themselves go off with prostitutesand make sacrifices with cult prostitutes.People without discernment are doomed.
