'Fuel' in the Bible

Look! It is given to the fire as fuel. The fire will consume two of its ends, and its middle will be charred. Is it useful for anything?

Therefore thus says the Lord Yahweh: {Just like} the wood of the vine among the trees of the forest which I gave to the fire for fuel, so I have given the inhabitants of Jerusalem.

You will be as fuel for the fire; your blood will be in the midst of the earth. You will not be remembered, for I, Yahweh, I have spoken.'"
