Numbers 1:49-53 Only thou shalt not number the tribe of Levi, neither take the sum of them among the children of Israel.

Darby⁽ⁱ⁾ ⁴⁹ Only thou shalt not number the tribe of Levi, neither take the sum of them among the children of Israel. ⁵⁰ But thou, appoint the Levites over the tabernacle of testimony, and over all the vessels thereof, and over all things that belong to it: they shall bear the tabernacle, and all its vessels; and they shall serve it, and round about the tabernacle shall they encamp; ⁵¹ and when the tabernacle setteth forward, the Levites shall take it down; and when the tabernacle encampeth, the Levites shall set it up; and the stranger that cometh near shall be put to death. ⁵² And the children of Israel shall encamp every man in his camp, and every man by his own standard, according to their hosts; ⁵³ but the Levites shall encamp round about the tabernacle of testimony, that there come not wrath upon the assembly of the children of Israel; and the Levites shall keep the charge of the tabernacle of testimony.
