Numbers 1:47-54 World English Bible (WEB)
47 But the Levites after the tribe of their fathers were not numbered among them. 48 For Yahweh spoke to Moses, saying, 49 “Only the tribe of Levi you shall not number, neither shall you take a census of them among the children of Israel; 50 but appoint the Levites over the Tabernacle of the Testimony, and over all its furnishings, and over all that belongs to it. They shall carry the tabernacle, and all its furnishings; and they shall take care of it, and shall encamp around it. 51 When the tabernacle is to move, the Levites shall take it down; and when the tabernacle is to be set up, the Levites shall set it up. The stranger who comes near shall be put to death. 52 The children of Israel shall pitch their tents, every man by his own camp, and every man by his own standard, according to their divisions. 53 But the Levites shall encamp around the Tabernacle of the Testimony, that there may be no wrath on the congregation of the children of Israel: and the Levites shall be responsible for the Tabernacle of the Testimony.”
54 Thus the children of Israel did. According to all that Yahweh commanded Moses, so they did.
Numbers 1:47-54 New International Version (NIV)
47 The ancestral tribe of the Levites, however, was not counted along with the others. 48 The Lord had said to Moses: 49 “You must not count the tribe of Levi or include them in the census of the other Israelites. 50 Instead, appoint the Levites to be in charge of the tabernacle of the covenant law—over all its furnishings and everything belonging to it. They are to carry the tabernacle and all its furnishings; they are to take care of it and encamp around it. 51 Whenever the tabernacle is to move, the Levites are to take it down, and whenever the tabernacle is to be set up, the Levites shall do it. Anyone else who approaches it is to be put to death. 52 The Israelites are to set up their tents by divisions, each of them in their own camp under their standard. 53 The Levites, however, are to set up their tents around the tabernacle of the covenant law so that my wrath will not fall on the Israelite community. The Levites are to be responsible for the care of the tabernacle of the covenant law.”
54 The Israelites did all this just as the Lord commanded Moses.
