Numbers 1:50-53

Thomson(i) 50 But thou shalt set the Levites over the tabernacle of the testimony, and over all the utensils thereof, and over all the things which are in it. They shall carry the tabernacle, and all its utensils, and they shall minister therein, and encamp about the tabernacle. 51 And when the tabernacle is to remove, the Levites shall take it down; and when the tabernacle is to be pitched, they shall set it up. And if any of another family come near, let him be put to death. 52 And when the Israelites encamp, every man in his station, and every man according to his command, with their army, 53 let the Levites encamp before them, around the tabernacle of the testimony, that there may be no lapse committed by the children of Israel; and that the Levites themselves may guard the tabernacle of the testimony.
