Ezekiel 39:12-14

12And seven months shall the house of Israel be burying them, that they may cleanse the land;

13and all the people of the land shall bury [them]; and it shall be to them for renown in the day that I shall be glorified, saith the Lord Jehovah.

14And they shall sever out men of continual employment to go through the land, who, with the passers-by, shall bury those that remain upon the face of the land, to cleanse it: at the end of seven months shall they make a search.
