Numbers 1:52-54 Tree of Life Version (TLV)
52 Bnei-Yisrael will encamp, each man with his own camp, each with his own standard, according to their own divisions. 53 The Levites are to camp around the Tabernacle of the Testimony, so that there will be no wrath unleashed on the community of Bnei-Yisrael. So the Levites are to maintain care of the Tabernacle of the Testimony.
54 So Bnei-Yisrael did—all that Adonai commanded Moses, so they did.
