Numbers 1:46-53

⁴⁶six hundred thousand and three thousand and five hundred and fifty.

⁴⁷But the Levites of the tribe of their family were not counted among the children of Israel.

⁴⁸And the Lord spoke to Moses, saying,

⁴⁹See, you shall not muster the tribe of Levi, and you shall not take their numbers, in the midst of the children of Israel.

⁵⁰And do you set the Levites over the tabernacle of witness, and over all its furniture, and over all things that are in it; and they shall do service in it, and they shall encamp round about the tabernacle.

⁵¹And in removing the tabernacle, the Levites shall take it down, and in pitching the tabernacle they shall set it up: and let the stranger that advances to touch it die.

⁵²And the children of Israel shall encamp, every man in his own order, and every man according to his company, with their host.

⁵³But let the Levites encamp round about the tabernacle of witness fronting it, and so there shall be no sin among the children of Israel; and the Levites themselves shall keep the guard of the tabernacle of witness.
