The wilderness of Judah.

If you ask where David was when he composed that Psalm, it is answered (1 Sam 24:1), "In the wilderness of En-gedi": and if you search further for the precise place, it was there where the castle Masada was afterward built. For I doubt not at all, that that place, as Josephus describes it, was the same with "the rocks of the wild goats." [1 Sam 24:3]

I appeal here to the maps and their authors, in whom 'En-gedi' and 'Masada' (and 'Lot's cave') are placed not very far from the utmost north cost of Asphaltites: let them say whether Idumea stretched out itself so far. If not, let them correct the interpreters whom we have named; and thought it be so, they might show by what authority they place those places there, and let them friendly correct me putting them far elsewhere.
