Numbers 1:48

⁴⁶Even all they that were numbered were six hundred thousand and three thousand and five hundred and fifty.

⁴⁷But the Levites after the tribe of their fathers were not numbered among them.

— Numbers 1:48 —

⁴⁹Only thou shalt not number the tribe of Levi, neither take the sum of them among the children of Israel:

⁵⁰But thou shalt 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 the vessels thereof; and they shall minister unto it, and shall encamp round about the tabernacle.
