“And the residue in length answerable to the holy Gift-offering shall be ten thousand eastward and ten thousand westward. And it shall be answerable to the holy Gift-offering. And its increase shall be for food for those who labour in the city. And those who labour in the city from all the tribes of Israel will till it.”
The land, on each side east and west of the city and the open space, measuring ten thousand each (by five thousand), will make up the other twenty thousand, which with the five thousand for the city and open space is adjacent to the twenty five thousand of the Levites' portion. This will be for the production of food for the city, which itself will be inhabited by members of all the tribes of Israel.
