Ezekiel 39:11-15

11And it shall come to pass in that day, [that] I will give unto Gog a place there for burial in Israel, the valley of the passers-by to the east of the sea; and it shall stop [the way] of the passers-by; and there shall they bury Gog and all the multitude; and they shall call it, Valley of Hamon-Gog.

12And seven months shall the house of Israel be burying them, that they may cleanse the land;

13and all the people of the land shall bury [them]; and it shall be to them for renown in the day that I shall be glorified, saith the Lord Jehovah.

14And they shall sever out men of continual employment to go through the land, who, with the passers-by, shall bury those that remain upon the face of the land, to cleanse it: at the end of seven months shall they make a search.

15And the passers-by shall pass through the land, and when [any] seeth a man's bone, he shall set up a sign by it, till the buriers have buried it in the Valley of Hamon-Gog.
