Numbers 26:52-56

The LORD said to Moses, “The land is to be allotted to them as an inheritance based on the number of names. To a larger group give a larger inheritance, and to a smaller group a smaller one; each is to receive its inheritance according to the number of those listed. Be sure that the land is distributed by lot. What each group inherits will be according to the names for its ancestral tribe. Each inheritance is to be distributed by lot among the larger and smaller groups.”
