Números 33:54

54 Distribute the land by lot, according to your clans. To a larger group give a larger inheritance, and to a smaller group a smaller one. Whatever falls to them by lot will be theirs. Distribute it according to your ancestral tribes.

54 And you will take up your heritage in the land by the decision of the Lord, to every family its part; the greater the family the greater its heritage, and the smaller the family the smaller will be its heritage; wherever the decision of the Lord gives to any man his part, that will be his; distribution will be made to you by your fathers' tribes.
