Ezekiel 39:12-16

For seven months the house of Israel will be burying them in order to cleanse the land. Yes, all the people of the land will bury them; and it will be to their renown on the day that I appear in My glory and brilliance,” says the Lord GOD. “They will elect men who will constantly go through the land, [men commissioned] to bury those who were passing through, those bodies that lie unburied on the surface of the ground, in order to cleanse it. At the end of seven months they will do a search. As those who pass through the land pass through and anyone sees a human bone, he will set up a marker beside it, until the buriers have buried it in the Valley of Hamon-gog. And even the name of the city will be Hamonah. In this manner they shall cleanse the land.” ’
