Ezekiel 39:9-10

9And they that dwell in the cities of Israel shall go forth, and shall set on fire and burn the weapons, both the shields and the bucklers, the bows and the arrows, and the javelins, and the spears, and they shall burn them with fire seven years:12 10So that they shall take no wood out of the field, neither cut down any out of the forests; for they shall burn the weapons with fire: and they shall lay waste those that wasted them, and rob those that robbed them, saith the Lord GOD.
