What does Ezekiel 39:14 mean?

And they shall set apart men of continual employment, that shall pass through the land, and, with them that pass through, those that bury them that remain upon the face of the land, to cleanse it: after the end of seven months shall they search.

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.

And they shall set apart men of continual employment, that shall pass through the land, and, with them that pass through, those that bury them that remain upon the face of the land, to cleanse it: after the end of seven months shall they search.

And they will put on one side men to do no other work but to go through the land and put in the earth the rest of those who are still on the face of the land, to make it clean: after seven months are ended they are to make a search.

And men for continual employment they separate, passing on through the land, burying with those passing by those who are left on the face of the earth, to cleanse it: at the end of seven months they search.

And they shall appoint men to go continually about the land, to bury and to seek out them that were remaining upon the face of the earth, that they may cleanse it: and after seven months they shall begin to seek.

And 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.
