'Fuel' in the Bible

Behold, it is cast into the fire for fuel; the fire hath devoured both the ends of it, and the midst of it is burned: is it profitable for any work?

Therefore thus saith the Lord Jehovah: As the vine-tree among the trees of the forest, which I have given to the fire for fuel, so will I give the inhabitants of Jerusalem.

Thou shalt be for fuel to the fire; thy blood shall be in the midst of the land; thou shalt be no more remembered: for I, Jehovah, have spoken it.
