Ezekiel 48:18-20

New Century Version

¹⁸ Along the long side of the holy area there will be left three miles on the east and three miles on the west. It will be used to grow food for the city workers. ¹⁹ The city workers from all the tribes of Israel will farm this land. ²⁰ This whole area will be square, seven miles by seven miles. You shall give to the Lord the holy share along with the city property.
