'Two thirds' in the Bible

“When you divide the land by lot as an inheritance, you must set aside a donation to the Lord, a holy portion of the land, 8⅓ miles long and 6⅔ miles wide. This entire tract of land will be holy.

“As the property of the city, you must set aside an area 1⅔ of a mile wide and 8⅓ miles long, adjacent to the holy donation of land. It will be for the whole house of Israel.

“The remaining area, 1⅔ of a mile wide and 8⅓ miles long, will be for common use by the city, for both residential and open space. The city will be in the middle of it.
