Vayikra 10:9-11

Orthodox Jewish Bible

⁹ Do not drink yayin nor strong drink, thou, nor thy banim with thee, when ye go into the Ohel Mo’ed, lest ye die; it shall be chukkat olam throughout your generations;

¹⁰ And that ye may put difference between kodesh and chol (common, profane), and between tameh (unclean) and tahor (clean);

¹¹ And that ye may teach the Bnei Yisroel all the chukkim which Hashem hath spoken unto them by the hand of Moshe.
