Numbers 33:54

and you shall divide their land, by lot, among your tribes. To those who are more numerous you shall give a larger possession; and to those who are fewer in number you shall give a smaller possession. On whatever place any one’s name falleth, there shall be his possession. According to the tribes of your families you shall possess it.

And ye shall inherit their land according to your tribes; to the greater number ye shall give the larger possession, and to the smaller ye shall give the less possession; to whatsoever part a man's name shall go forth by lot, there shall be his property: ye shall inherit according to the tribes of your families.
