Ezekiel 20:18-20

“And I said to their children in the wilderness, ‘Do not walk in the statutes of your fathers, nor keep their rules, nor defile yourselves with their idols. I am the LORD your God; walk in my statutes, and be careful to obey my rules, and keep my Sabbaths holy that they may be a sign between me and you, that you may know that I am the LORD your God.’
