Ezekiel 39:12-16

It will take seven months for the people of Israel to bury the bodies and cleanse the land. Everyone in Israel will help, for it will be a glorious victory for Israel when I demonstrate my glory on that day, says the Sovereign LORD. “After seven months, teams of men will be appointed to search the land for skeletons to bury, so the land will be made clean again. Whenever bones are found, a marker will be set up so the burial crews will take them to be buried in the Valley of Gog’s Hordes. (There will be a town there named Hamonah, which means ‘horde.’) And so the land will finally be cleansed.
