'Thorn bushes' in the Bible

“If a fire breaks out and spreads to thorn bushes, so that stacked grain or the standing grain or the field itself is consumed, he who started the fire shall surely make restitution.

For as the crackling of thorn bushes under a pot,So is the laughter of the fool;And this too is futility.

They will all come and settle on the steep ravines, on the ledges of the cliffs, on all the thorn bushes and on all the watering places.

You will know them by their fruits. Grapes are not gathered from thorn bushes nor figs from thistles, are they?
