Judges
And the hand of Midian prevailed against Israel: and because of the Midianites the children of Israel made them the dens which are in the mountains, and caves, and strong holds.
1 Samuel
And David abode in the wilderness in strong holds, and remained in a mountain in the wilderness of Ziph. And Saul sought him every day, but God delivered him not into his hand.
Then came up the Ziphites to Saul to Gibeah, saying, Doth not David hide himself with us in strong holds in the wood, in the hill of Hachilah, which is on the south of Jeshimon?
1 Chronicles
And of the Gadites there separated themselves unto David into the hold to the wilderness men of might, and men of war fit for the battle, that could handle shield and buckler, whose faces were like the faces of lions, and were as swift as the roes upon the mountains;
Isaiah
He shall dwell on high: his place of defence shall be the munitions of rocks: bread shall be given him; his waters shall be sure.
Jeremiah
Kerioth is taken, and the strong holds are surprised, and the mighty men's hearts in Moab at that day shall be as the heart of a woman in her pangs.
The mighty men of Babylon have forborn to fight, they have remained in their holds: their might hath failed; they became as women: they have burned her dwellingplaces; her bars are broken.
Ezekiel
Say thou thus unto them, Thus saith the Lord GOD; As I live, surely they that are in the wastes shall fall by the sword, and him that is in the open field will I give to the beasts to be devoured, and they that be in the forts and in the caves shall die of the pestilence.
