What are the strongholds in the wilderness in which David stayed?
1 Samuel 23:14 (ESV)
14And David remained in the strongholds in the wilderness, in the hill country of the wilderness of Ziph. And Saul sought him every day, but God did not give him into his hand.
Strongholds in this context refers to natural shelters and hiding places in the wilderness, like suitable caves and rocky outcrops.
