'Smaller' in the Bible
According to the lot shall their inheritance be divided between the larger and the smaller.
You shall inherit the land by lot according to your families; to the large tribe you shall give a larger inheritance, and to the small tribe you shall give a smaller inheritance. Wherever the lot falls to any man, that shall be his. According to the tribes of your fathers you shall inherit.
As for the cities, you shall give from the possession of the Israelites, from the larger tribes you shall take many and from the smaller tribes few; each tribe shall give of its cities to the Levites in proportion to its inheritance.
