Bamidbar 1:49-51

Orthodox Jewish Bible

⁴⁹ Only thou shalt not number the tribe of Levi, neither take the sum of them among the Bnei Yisroel;

⁵⁰ But thou shalt appoint the Levi’im over the Mishkan HaEdut and over all the vessels thereof, and over all things that belong to it; they shall bear the Mishkan, and all the vessels thereof; and they shall take care of it, and shall encamp round about the Mishkan.

⁵¹ And when the Mishkan setteth forward, the Levi’im shall take it down; and when the Mishkan is to be pitched, the Levi’im shall set it up; and the zar (stranger, outsider, unauthorized party) that cometh nigh shall be put to death.
