Ezekiel 20:18-20

New Revised Standard Version, Anglicised Catholic Edition

¹⁸ I said to their children in the wilderness, Do not follow the statutes of your parents, nor observe their ordinances, nor defile yourselves with their idols. ¹⁹ I the Lord am your God; follow my statutes, and be careful to observe my ordinances, ²⁰ and hallow my sabbaths that they may be a sign between me and you, so that you may know that I the Lord am your God.
