Leviticus 20:13-14

“ ‘If a man has sexual relations with a man as one does with a woman, both of them have done what is detestable. They are to be put to death; their blood will be on their own heads. “ ‘If a man marries both a woman and her mother, it is wicked. Both he and they must be burned in the fire, so that no wickedness will be among you.
