Ezekiel 39:9-10

9Then those who dwell in the cities of Israel will go out, kindle fires, and burn up the weapons—the bucklers and shields, the bows and arrows, the clubs and spears. For seven years they will use them for fuel. 10They will not gather wood from the countryside or cut it from the forests, for they will use the weapons for fuel. They will loot those who looted them and plunder those who plundered them, declares the Lord GOD.
