Ezekiel 39:9-10

9“‘Then those who live in the cities of Israel will go out and use the weapons for kindling – the shields, bows and arrows, war clubs and spears – they will burn them for seven years.

10They will not need to take wood from the field or cut down trees from the forests, because they will make fires with the weapons. They will take the loot from those who looted them and seize the plunder of those who plundered them, declares the sovereign Lord.
