Numbers 1:51-53

Revised Standard Version Catholic Edition

⁵¹ When the tabernacle is to set out, the Levites shall take it down; and when the tabernacle is to be pitched, the Levites shall set it up. And if any one else comes near, he shall be put to death. ⁵² The people of Israel shall pitch their tents by their companies, every man by his own camp and every man by his own standard; ⁵³ but the Levites shall encamp around the tabernacle of the testimony, that there may be no wrath upon the congregation of the people of Israel; and the Levites shall keep charge of the tabernacle of the testimony.”
