Shemot 19:22-24

Orthodox Jewish Bible

²² And let the kohanim also, which come near to Hashem, set themselves apart as kodesh, lest Hashem break forth upon them.

²³ And Moshe said unto Hashem, HaAm cannot come up to Mt. Sinai; for You Yourself charged us, saying, Establish boundaries for HaHar, and set it apart as kodesh.

²⁴ And Hashem said unto him, Away, get thee down, and thou shalt come up, thou, and Aharon with thee; but let not the kohanim and HaAm push through to come up unto Hashem, lest He break forth upon them.
