Ezekiel 39:11-15

11“‘On that day I will assign Gog a grave in Israel. It will be the valley of those who travel east of the sea; it will block the way of the travelers. There they will bury Gog and all his horde; they will call it the valley of Hamon-Gog.

12For seven months Israel will bury them, in order to cleanse the land.

13All the people of the land will bury them, and it will be a memorial for them on the day I magnify myself, declares the sovereign Lord.

14They will designate men to scout continually through the land, burying those who remain on the surface of the ground, in order to cleanse it. They will search for seven full months.

15When the scouts survey the land and see a human bone, they will place a sign by it, until those assigned to burial duty have buried it in the valley of Hamon-Gog.
