Ezekiel 39:14-16

39:14 They will designate men to scout continually through the land, burying those who remain on the surface of the ground, in order to cleanse it. They will search for seven full months. 39:15 When the scouts survey the land and see a human bone, they will place a sign by it, until those assigned to burial duty have buried it in the valley of Hamon-Gog. 39:16 (A city by the name of Hamonah will also be there.) They will cleanse the land.’
