Treasury of Scripture Knowledge
If there is a man who takes his sister, his father’s daughter or his mother’s daughter, so that he sees her nakedness and she sees his nakedness, it is a disgrace; and they shall be cut off in the sight of the sons of their people. He has uncovered his sister’s nakedness; he bears his guilt.
Cursed is he who lies with his sister, the daughter of his father or of his mother.’ And all the people shall say, ‘Amen.’
2 Samuel 13:11
When she brought them to him to eat, he
took hold of her and said to her, “Come, lie with me, my sister.”
One has committed abomination with his
neighbor’s wife and another has lewdly defiled his daughter-in-law. And another in you has humbled his sister, his father’s daughter.
