John Wesley on Joshua 15:19

A blessing - That is, a gift, as that word signifies, Gen 33:11. A south land - That is, a dry land, much exposed to the south wind, which in those parts was very hot and drying, as coming from the deserts of Arabia. Springs of water - That is, a field, wherein are springs of water, which in that country were of great price; she begs a well moistened field, which also might give some relief to that which was dry and barren. Upper and nether springs - Or two fields, one above and the other below that south and dry ground which she complained of, that by this means it might be watered on both sides.
