Numbers 1:50-52

American Standard Version

⁵⁰ but appoint thou the Levites over the tabernacle of the testimony, and over all the furniture thereof, and over all that belongeth to it: they shall bear the tabernacle, and all the furniture 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, according to their hosts.
