Leviticus 18:1-5

The LORD said to Moses, “Speak to the Israelites and say to them: ‘I am the LORD your God. You must not do as they do in Egypt, where you used to live, and you must not do as they do in the land of Canaan, where I am bringing you. Do not follow their practices. You must obey my laws and be careful to follow my decrees. I am the LORD your God. Keep my decrees and laws, for the person who obeys them will live by them. I am the LORD.
