Leviticus 18:8–9

¹¹And the man that lieth with his father’s wife hath uncovered his father’s nakedness: both of them shall surely be put to death; their blood shall be upon them.

¹IT is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father’s wife.

³⁰¶ A man shall not take his father’s wife, nor discover his father’s skirt.

²⁰Cursed be he that lieth with his father’s wife; because he uncovereth his father’s skirt. And all the people shall say, Amen.

⁷That pant after the dust of the earth on the head of the poor, and turn aside the way of the meek: and a man and his father will go in unto the same maid, to profane my holy name:

⁴Unstable as water, thou shalt not excel; because thou wentest up to thy father’s bed; then defiledst thou it: he went up to my couch.

²¹And Ahithophel said unto Absalom, Go in unto thy father’s concubines, which he hath left to keep the house; and all Israel shall hear that thou art abhorred of thy father: then shall the hands of all that are with thee be strong.

²²So they spread Absalom a tent upon the top of the house; and Absalom went in unto his father’s concubines in the sight of all Israel.

¹⁰In thee have they discovered their fathers’ nakedness: in thee have they humbled her that was set apart for pollution.

²²And it came to pass, when Israel dwelt in that land, that Reuben went and lay with Bilhah his father’s concubine: and Israel heard it. Now the sons of Jacob were twelve:

¹⁷And if a man shall take his sister, his father’s daughter, or his mother’s daughter, and see her nakedness, and she see his nakedness; it is a wicked thing; and they shall be cut off in the sight of their people: he hath uncovered his sister’s nakedness; he shall bear his iniquity.

²²Cursed be he that lieth with his sister, the daughter of his father, or the daughter of his mother. And all the people shall say, Amen.

¹¹And one hath committed abomination with his neighbour’s wife; and another hath lewdly defiled his daughter in law; and another in thee hath humbled his sister, his father’s daughter.

¹¹And when she had brought them unto him to eat, he took hold of her, and said unto her, Come lie with me, my sister.

¹²And she answered him, Nay, my brother, do not force me; for no such thing ought to be done in Israel: do not thou this folly.

¹³And I, whither shall I cause my shame to go? and as for thee, thou shalt be as one of the fools in Israel. Now therefore, I pray thee, speak unto the king; for he will not withhold me from thee.

¹⁴Howbeit he would not hearken unto her voice: but, being stronger than she, forced her, and lay with her.

¹¹The nakedness of thy father’s wife’s daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.
