Yechezkel 20:18-20

Orthodox Jewish Bible

¹⁸ But I said unto their banim in the midbar, Walk ye not in the chukkot of avoteichem, neither be shomer over their mishpatim, nor make yourselves tameh with their gillulim (idols).

¹⁹ I am Hashem Eloheichem; walk in My chukkot, and be shomer over My mishpatim, and do them;

²⁰ And be shomer shabbos over My Shabbatot, keeping them kodesh; and they shall be an Ot between Me and you, that ye may know that I am Hashem Eloheichem .
