Leviticus 20:20-23

²⁰And if a man lie with the wife of his father’s brother he hath uncovered the nakedness of his father’s brother; they shall receive for their guilt without children shall they die.

²¹And if man take his brother’s wife, a thing to be kept aloof from, (merachaka,) he bath uncovered the nakedness of his brother, they shall be childless.

²²But keep you all My statutes and all My judgments, and do them, that the land into which I bring you to dwell may not cast you out.

²³You shall not walk in the laws of the peoples whom I drive away from before you; for they have committed all these thin, and My Word hath abhorred them.
