'Fuel' in the Bible

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

Therefore thus says the Lord Yahweh: 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.

You shall be for fuel to the fire; your blood shall be in the midst of the land; you shall be remembered no more: for I, Yahweh, have spoken it.
