Numbers 1:50-52

King James Version

⁵⁰ But 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.

⁵¹ And when the tabernacle setteth 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 cometh nigh shall be put to death.

⁵² And the children of Israel shall pitch their tents, every man by his own camp, and every man by his own standard, throughout their hosts.
