Ezekiel 39:12-16

For seven months the house of Israel will be burying them, in order to cleanse the land. Indeed all the people of the land will be burying, and they will gain renown for it on the day that I am glorified,” says the Lord GOD. “They will set apart men regularly employed, with the help of a search party, to pass through the land and bury those bodies remaining on the ground, in order to cleanse it. At the end of seven months they will make a search. The search party will pass through the land; and when anyone sees a man’s bone, he shall set up a marker by it, till the buriers have buried it in the Valley of Hamon Gog. The name of the city will also be Hamonah. Thus they shall cleanse the land.” ’
