TSK · Leviticus 18:9

The nakednesse of thy fathers wiues daughter begotten of thy father, which is thy sister: thou shalt not discouer her nakednesse.

Cursed be he that lieth with his sister, the daughter of his father, or ye daughter of his mother: and al the people shal say, Amen.

And she aunswered him: Nay my brother, do not force me, for there hath no such thing ben done in Israel: Do not thou this folly.
