Ezekiel 39:9-12 New King James Version (NKJV)

9. “Then those who dwell in the cities of Israel will go out and set on fire and burn the weapons, both the shields and bucklers, the bows and arrows, the javelins and spears; and they will make fires with them for seven years.

10. They will not take wood from the field nor cut down any from the forests, because they will make fires with the weapons; and they will plunder those who plundered them, and pillage those who pillaged them,” says the Lord God.

11. “It will come to pass in that day that I will give Gog a burial place there in Israel, the valley of those who pass by east of the sea; and it will obstruct travelers, because there they will bury Gog and all his multitude. Therefore they will call it the Valley of Hamon Gog.

12. For seven months the house of Israel will be burying them, in order to cleanse the land.
