The fields. The original is in the singular. We are not necessarily, therefore, to suppose that the land was mapped out into divisions analogous to our fields. Our word "land" would more accurately represent the meaning of the original, which refers to the arable and pasture land in the neighbourhood of the city, with the agricultural villages or homesteads dotted about it.
Keil contends that the Levites only received as many houses within the city as they needed, and that the rest belonged to Caleb. Bahr, moreover ('Symbolik,' 2:49), supposed that the Levites dwelt with the other inhabitants of the city, and that the pasture land within the distance of 2,000 paces from the city was reserved for them, the rest of the land belonging to the inhabitants of the tribe (see note on Gezer, Joshua 10:33).
This seems the most probable explanation. The land in general was owned by the descendants of Caleb. But the Levites had certain pastures reserved for them, whither they drove their cattle (see note on suburbs, Joshua 14:4).
The special information about Hebron here again is worthy of notice. It is copied by the author of 1 Chronicles in 1혻Chronicles 6:1-81.
