Then came up the Ziphites to Saul to Gibeah, saying, Doesn't David hide himself with us in the strongholds in the wood, in the hill of Hachilah, which is on the south of the desert?
"The strongholds of Horesh, on the hill of Hachilah"  (1 Samuel 23:19). G. W. Grogan of Glasgow identifies Horesh merely as "a place in the wilderness of Judea."[15] J. D. Douglas identified "Hachilah" as, "a hill in the wilderness of Judah where David was hidden when the Ziphites plotted to betray him to Saul.  The site is not accurately known but generally regarded as being near Dahret el Kola, between Ziph and Engedi."[16]
