'Thorn hedges' in the Bible

Whose harvest, the hungry, eateth up, and, even out of thorn hedges, he taketh it, and the snare gapeth for their substance.

And they shall come, and shall rest all of them in the desolate valleys, and in the clefts of the rocks, and upon all thorn-hedges, and upon all pastures.

Therefore as truly as I live, sayeth the LORD of Hosts the God of Israel, Moab shall be as Sodom, and Ammon as Gomorrah: even dry thorn hedges, salt pits and perpetual wilderness. The residue of my folk shall spoil them, the remnant of my people shall have them in possession.
