Leviticus 18:3-6

³You shall not do according to the custom of the land of Egypt, in which you dwelt: neither shall you act according to the manner of the country of Chanaan, into which I will bring you, nor shall you walk in their ordinances.

⁴You shall do my judgments, and shall observe my precepts, and shall walk in them. I am the Lord your God.

⁵Keep my laws and my judgments, which if a man do, he shall live in them. I am the Lord.

⁶No man shall approach to her that is near of kin to him, to uncover her nakedness. I am the Lord.
