'Caves' in the Bible

The hand of Midian prevailed against Israel; and because of Midian the children of Israel made them the dens which are in the mountains, and the caves, and the strongholds.

When the men of Israel saw that they were in a strait (for the people were distressed), then the people did hide themselves in caves, and in thickets, and in rocks, and in coverts, and in pits.

Men shall go into the caves of the rocks, and into the holes of the earth, from before the terror of Yahweh, and from the glory of his majesty, when he arises to shake the earth mightily.

You shall tell them, Thus says the Lord Yahweh: As I live, surely those who are in the waste places shall fall by the sword; and him who is in the open field will I give to the animals to be devoured; and those who are in the strongholds and in the caves shall die of the pestilence.

The lion tore in pieces enough for his cubs, and strangled for his lionesses, and filled his caves with the kill, and his dens with prey.
