The Gog-Magog War

Ezekiel, 39: 

'[...]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 Hamongog. And also the name of the city shall be Hamonah. Thus shall they cleanse the land.'
