11 And the Lord said to Moses, 12 See, I have taken the Levites out of the children of Israel to be mine in place of the first sons of the children of Israel; 13 For all the first sons are mine; on the day when I put to death all the first sons in the land of Egypt, I took for myself every first male birth of man and beast. They are mine; I am the Lord.
14 And the Lord said to Moses in the waste land of Sinai, 15 Let all the children of Levi be numbered by their families and their fathers' houses; let every male of a month old and over be numbered. 16 So Moses did as the Lord said, numbering them as he had been ordered. 17 These were the sons of Levi by name: Gershon and Kohath and Merari. 18 And these are the names of the sons of Gershon, by their families: Libni and Shimei. 19 And the sons of Kohath, by their families: Amram and Izhar and Hebron and Uzziel. 20 And the sons of Merari by their families: Mahli and Mushi. These are the families of the Levites in the order of their fathers' houses. 21 From Gershon come the Libnites and the Shimeites; these are the families of the Gershonites. 22 Those who were numbered of them, the males from one month old and over, were seven thousand, five hundred. 23 The tents of the Gershonites are to be placed at the back of the House, to the west. 24 The chief of the Gershonites is Eliasaph, the son of Lael. 25 In the Tent of meeting, the Gershonites are to have the care of the House, and the Tent with its cover, and the veil for the door of the Tent of meeting, 26 And the hangings for the open space round the House and the altar, and the curtain for its doorway, and all the cords needed for its use. 27 From Kohath come the Amramites and the Izharites and the Hebronites and the Uzzielites; these are the families of the Kohathites. 28 Those who were numbered of them, the males from one month old and over, were eight thousand, six hundred, who were responsible for the care of the holy place. 29 The tents of the Kohathites are to be placed on the south side of the House. 30 Their chief is Elizaphan, the son of Uzziel. 31 In their care are the ark, and the table, and the lights, and the altars, and all the vessels used in the holy place, and the veil, and all they are used for. 32 Eleazar, the son of Aaron the priest, will be head over all the Levites and overseer of those responsible for the care of the holy place. 33 From Merari come the Mahlites and the Mushites; these are the families of Merari. 34 Those who were numbered of them, the males of a month old and over, were six thousand, two hundred. 35 The chief of the families of Merari was Zuriel, the son of Abihail: their tents are to be placed on the north side of the House. 36 And in their care are to be all the boards of the Tent, with their rods and pillars and bases, and all the instruments, and all they are used for, 37 And the pillars of the open space round it, with their bases and nails and cords. 38 And those whose tents are to be placed on the east side of the House in front of the Tent of meeting, looking to the dawn, are Moses and Aaron and his sons, who will do the work of the holy place for the children of Israel; and any strange person who comes near will be put to death.

Commentary on Numbers 3:1-13
(Read Numbers 3:1-13)
There was much work belonging to the priests' office, and there were now only Aaron and his two sons to do it; God appoints the Levites to attend them. Those whom God finds work for, he will find help for. The Levites were taken instead of the first-born. When He that made us, saves us, as the first-born of Israel were saved, we are laid under further obligations to serve him faithfully. God's right to us by redemption, confirms the right he has to us by creation.
Commentary on Numbers 3:14-39
(Read Numbers 3:14-39)
The Levites were in three classes, according to the sons of Levi; Gershon, Kohath, and Merari; and these were subdivided into families. The posterity of Moses were not at all honoured or privileged, but stood upon the level with other Levites; thus it was plain, that Moses did not seek the advancement of his own family, or to secure any honours to it. The tribe of Levi was by much the least of all the tribes. God's chosen are but a little flock in comparison with the world.
