Ezekiel 39:11-15

And it shall come to pass in that day, that I will give unto Gog a place there of graves in Israel, the valley of the passengers on the east of the sea: and it shall stop the noses of the passengers: and there shall they bury Gog and all his multitude: and they shall call it The valley of Hamon-gog.

And seven months shall the house of Israel be burying of them, that they may cleanse the land.

Yea, all the people of the land shall bury them; and it shall be to them a renown the day that I shall be glorified, saith the Lord GOD.

And they shall sever out men of continual employment, passing through the land to bury with the passengers those that remain upon the face of the earth, to cleanse it: after the end of seven months shall they search.

And the passengers that pass through the land, when any seeth a man’s bone, then shall he set up a sign by it, till the buriers have buried it in the valley of Hamon-gog.
