Leviticus 18:1-5

And Jehovah spake unto Moses, saying, Speak unto the children of Israel, and say unto them, I am Jehovah your God. After the doings of the land of Egypt, wherein ye dwelt, shall ye not do: and after the doings of the land of Canaan, whither I bring you, shall ye not do; neither shall ye walk in their statutes. Mine ordinances shall ye do, and my statutes shall ye keep, to walk therein: I am Jehovah your God. Ye shall therefore keep my statutes, and mine ordinances; which if a man do, he shall live in them: I am Jehovah.
