Numbers 1:46-54
1:46 And all those numbered totaled 603,550.
The Exemption of the Levites
1:47 But the Levites, according to the tribe of their fathers, were not numbered among them.
1:48 The Lord had said to Moses,
1:49 “Only the tribe of Levi you must not number or count with the other Israelites.
1:50 But appoint the Levites over the tabernacle of the testimony, over all its furnishings and over everything in it. They must carry the tabernacle and all its furnishings; and they must attend to it and camp around it.
1:51 Whenever the tabernacle is to move, the Levites must take it down, and whenever the tabernacle is to be reassembled, the Levites must set it up. Any unauthorized person who approaches it must be killed.
1:52 “The Israelites will camp according to their divisions, each man in his camp, and each man by his standard.
1:53 But the Levites must camp around the tabernacle of the testimony, so that the Lord’s anger will not fall on the Israelite community. The Levites are responsible for the care of the tabernacle of the testimony.”
1:54 The Israelites did according to all that the Lord commanded Moses – that is what they did.
