Ezekiel 39:9-10

9“ ‘Then those who live in the towns of Israel will go out and use the weapons for fuel and burn them up—the small and large shields, the bows and arrows, the war clubs and spears. For seven years they will use them for fuel. 10They will not need to gather wood from the fields or cut it from the forests, because they will use the weapons for fuel. And they will plunder those who plundered them and loot those who looted them, declares the Sovereign Lord.
