Ezekiel 39:14

And they shall sever out men of continual employment, passing through the land to bury with the passengers those that remain upon the face of the earth, to cleanse it: after the end of seven months shall they search.

They shall sever out men of continual employment, passing through the land, to bury with the passengers those that remain upon the face of the earth. The men employed continually in the burying of the bodies "remaining on the surface of the earth" were to be helped by those happening to pass by; all were to combine.

After the end of seven months shall they search - to see if the work was complete (Munster).
