'Thickets' in the Bible

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.

For wickedness burneth as the fire; it devoureth the briers and thorns; yea, it kindleth in the thickets of the forest, and they roll upward in a column of smoke.

And he will cut down the thickets of the forest with iron, and Lebanon shall fall by a mighty one.

Every city fleeth for the noise of the horsemen and bowmen; they go into the thickets, and climb up upon the rocks: every city is forsaken, and not a man dwelleth therein.
