a bone

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 it will redound to their honor on the day that I show my glory, says the Lord GOD.
14
They will set apart men to pass through the land continually and bury those remaining upon the face of the land, so as to cleanse it; at the end of seven months they will make their search.
15
And when these pass through the land and any one sees a man's bone, then he shall set up a sign by it, till the buriers have buried it in the Valley of Hamon-gog.

(A city Hamo'nah is there also.) Thus shall they cleanse the land.
