'Fuel' in the Bible

So Elisha turned back, took the pair of oxen, sacrificed them, boiled their flesh using the farm implements for fuel, and gave the food to the people with him. Then he got up, followed Elijah, and became his servant.

For every boot of the tramping soldier in battle tumult and every garment rolled in blood will be used for burning as fuel for a fire.

From the wrath of the LORD of the Heavenly Armies the land has been scorched, and the people have become like fuel for the fire; no one will spare his neighbor.

Lebanon would not provide enough fuel, nor are its animals enough for a burnt offering.

You are to eat it as barley cakes and bake it right in front of them, using dried human dung for cooking fuel."

You'll be fuel for the conflagration. Your blood will be spilled throughout the land. You won't be remembered anymore, now that I, the LORD, have spoken."
