Numbers 1:51-53

Holman Christian Standard Bible

⁵¹ Whenever the tabernacle is to move, the Levites are to take it down, and whenever it is to stop at a campsite, the Levites are to set it up. Any unauthorized person who comes near it must be put to death.^(A)

⁵² “The Israelites are to camp by their military divisions, each man with his encampment and under his banner. ⁵³ The Levites are to camp around the tabernacle of the testimony and watch over it, so that no wrath will fall on the Israelite community.”^(B)
