a mountain: Psalms 11:1-3
the wilderness: Ziph is mentioned in Joshua with Carmel and Maon, near which it seems to have been situated; and as we have mention of Carmel and Maon in the history of David, as adjoining to Ziph, it cannot be doubted that by the Ziph, in the wilderness of which David now lay, and where was the hill of Hachilah, is to be understood Ziph near Carmel and Maon. Joshua 15:24, Joshua 15:55
