Numbers 1:51-53 When the tabernacle is to journey the Levites shall take it down; and when the tabernacle is to encamp the Levites shall set it up. But any alien who comes near shall be put to death.

CLV⁽ⁱ⁾ ⁵¹ When the tabernacle is to journey the Levites shall take it down; and when the tabernacle is to encamp the Levites shall set it up. But any alien who comes near shall be put to death. ⁵² The sons of Israel will encamp by their militia hosts, each man on his campsite and each under his standard. ⁵³ Yet the Levites shall encamp around the tabernacle of the testimony so that no wrath may come on the congregation of the sons of Israel. The Levites will keep guard of the tabernacle of the testimony.
