Albert Barnes Commentary Joshua 15:19

"And she said, Give me a blessing; for that thou hast set me in the land of the South, give me also springs of water. And he gave her the upper springs and the nether springs." — Joshua 15:19 (ASV)

A south land - This term (“negeb”), which is often equivalent to a proper name (Joshua 15:21), signifying the well-defined district that formed the south of the promised land (Numbers 13:17 note), seems here used in its more general sense (Psalms 126:4), for a dry or barren land. The rendering of this passage adopted by the Septuagint, several versions, commentators, and others, “you have given me into a south land,” that is, “have given me in marriage into a south land,” is forced; the construction of the verb “to give,” with two accusatives, is natural and common to many languages.

Springs of water - The Hebrew words מים גלה gûllâh mayı̂m are found only here and in the parallel passage (Judges 1:15). Hence, some take it as a proper name, “Gulloth-maim,” which, like Beth-horon (Joshua 16:3, Joshua 16:5), was applied to two distinct but adjoining places—distinguished as “the upper” and “the lower.” The tract in question was no doubt a mountain slope that had springs both on its higher and lower ground, possibly the modern “Kurmul.”
