Leviticus 18:8

And 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.

It 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.

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

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

That 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:

Unstable 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.

And 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:

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