Ezekiel 20:18-20

But I said unto their children in the wilderness, Walk ye not in the statutes of your fathers, neither observe their judgments, nor defile yourselves with their idols: I {am} the LORD your God; walk in my statutes, and keep my judgments, and do them; And hallow my sabbaths; and they shall be a sign between me and you, that ye may know that I {am} the LORD your God.
