'Fuel' in the Bible

For every battle of the warrior is with confused noise, and garments rolled in blood; but this shall be with burning and fuel of fire.

Through the wrath of the LORD of hosts is the land darkened, and the people shall be as the fuel of the fire: no man shall spare his brother.

Lebanon is not enough for fuel,or its animals enough for a burnt offering.

It serves as fuel for man.He takes some of it and warms himself;also he kindles a fire and bakes bread;he even makes it into a god and worships it;he makes an idol from it and bows down to it.
