Numbers 1:51-53

Amplified Bible, Classic Edition

⁵¹ When the tabernacle is to go forward, the Levites shall take it down, and when the tabernacle is to be pitched, the Levites shall set it up. And the excluded [any not of the tribe of Levi] who approach the tabernacle shall be put to death.

⁵² The Israelites shall pitch their tents by their companies, every man by his own camp and every man by his own [tribal] standard.

⁵³ But the Levites shall encamp around the tabernacle of the Testimony, that there may be no wrath upon the congregation of the Israelites; and the Levites shall keep charge of the tabernacle of the Testimony.
