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

50 But you shall 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 camp round about the tabernacle.

51 And when the tabernacle sets forward, the Levites shall take it down: and when the tabernacle is to be pitched, the Levites shall set it up: and the stranger that comes nigh shall be put to death.
