'Straw' in the Bible

Therefore, as flames of fire devour straw, as dry grass collapses in flames, so their root will be rotten, and their blossom will blow away like dust, because they have rejected the instruction of the LORD of the Heavenly Armies, and have despised the word of the Holy One of Israel.

The cow and the bear will graze, and their young will lie down together, and the lion will eat straw like the ox.

For the LORD's power will rest on this mountain, but the Moabites will be trodden down beneath him, just as straw is trodden down in the slime of a manure pit.

"The wolf and the lamb will feed together, and the lion will eat straw like the ox; but as for the serpent its food will be dust! They won't harm or destroy on my entire holy mountain," says the LORD.
