People will be continually employed in cleansing the land. They will spread out across the land and, along with others, they will bury any bodies that are lying on the ground. "After the seven months they will carry out a more detailed search."
NIV
And they shall set apart men to work continually who shall pass through the land, men commissioned to bury, with the help of those who are passing by, those bodies that lie unburied on the face of the ground, in order to cleanse the land. After the end of seven months they shall make their search.
AMP
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.
