Numbers 1:48 WBT

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

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

⁴⁸  For the LORD had spoken to Moses, saying,

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

⁵⁰  But thou shalt appoint the Levites over the tabernacle of testimony, and over all its vessels, and over all things that [belong] to it: they shall bear the tabernacle, and all its vessels, and they shall minister to it, and shall encamp around the tabernacle.
