Numbers 26:55

53“To these the land shall be divided for an inheritance according to the number of names.

54To the more you shall give the more inheritance, and to the fewer you shall give the less inheritance. To everyone according to those who were counted of him shall his inheritance be given.

55Notwithstanding, the land shall be divided by lot. According to the names of the tribes of their fathers they shall inherit.

56According to the lot shall their inheritance be divided between the more and the fewer.”

57These are those who were counted of the Levites after their families: of Gershon, the family of the Gershonites; of Kohath, the family of the Kohathites; of Merari, the family of the Merarites.
