Numbers 33:53-54

and ye shall dispossess the inhabitants of the land, and dwell therein: for I have given you the land to possess it. 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.
