Leviticus 20:16-17

MSTC(i) 16 If a woman go unto a beast and lie down thereto: thou shalt kill the woman and the beast also they shall die, and their blood be upon their heads. 17 "'If a man take his sister, his father's daughter or his mother's daughter, and see her privities, and she see his privities also: it is a wicked thing. Therefore let them perish in the sight of their people; he hath seen his sister's secretness, he shall therefore bear his sin.
