Numbers 33:54

And you are to divide the land by lot according to your clans. Give a larger inheritance to a larger clan and a smaller inheritance to a smaller one. Whatever falls to each one by lot will be his. You will receive an inheritance according to the tribes of your fathers.

And ye shall divide the land by lot for an inheritance among your families: and to the more ye shall give the more inheritance, and to the fewer ye shall give the less inheritance: every man’s inheritance shall be in the place where his lot falleth; according to the tribes of your fathers ye shall inherit.
