Ezekiel 39:12-16
12 “‘For seven months the house of Israel will be burying them in order to cleanse the land.
13 All the people of the land will bury them, and the day I am glorified will be a memorable day for them, declares the Sovereign Lord.
14 “‘Men will be regularly employed to cleanse the land. Some will go throughout the land and, in addition to them, others will bury those that remain on the ground. At the end of the seven months they will begin their search.
15 As they go through the land and one of them sees a human bone, he will set up a marker beside it until the gravediggers have buried it in the Valley of Hamon Gog.
16 (Also a town called Hamonah will be there.) And so they will cleanse the land.’
