'Thickets' in the Bible

And the men of Israel saw that they were in a strait (for the people were distressed); and the people hid themselves in caves, and in thickets, and in cliffs, and in strongholds, and in pits.

For wickedness burneth as a fire: it devoureth briars and thorns, and kindleth in the thickets of the forest, and they go rolling up like a pillar of smoke.

and he shall make clearings in the thickets of the forest with iron; and Lebanon shall fall by a mighty one.

At the noise of the horsemen and bowmen, every city fleeth; they go into the thickets, and climb up upon the rocks: every city is forsaken and no man dwelleth therein.
