Ezekiel 39:9-10

9“Then the people in the towns of Israel will go out and pick up your small and large shields, bows and arrows, javelins and spears, and they will use them for fuel. There will be enough to last them seven years!

10They won’t need to cut wood from the fields or forests, for these weapons will give them all the fuel they need. They will plunder those who planned to plunder them, and they will rob those who planned to rob them, says the Sovereign Lord.
