Bamidbar 18:3-5

Orthodox Jewish Bible

³ And they shall stand your guard duty, and the duty of Kol HaOhel; only they shall not come near the Klei HaKodesh and the Mizbe’ach, that neither they, nor ye also, die.

⁴ And they shall be joined unto thee, and stand guard duty of the Ohel Mo’ed, for kol Avodat HaOhel; and a zar shall not encroach unto you.

⁵ And ye shall stand guard of HaKodesh, and stand guard of the Mizbe’ach; that there be no Ketzef (Wrath) any more upon the Bnei Yisroel.
