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 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 to it, and shall encamp 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 near shall be put to death.
