Yechezkel 48:17-19

Orthodox Jewish Bible

¹⁷ And the migrash (open land) of the Ir shall extend toward the north two hundred and fifty [cubits], and toward the south two hundred and fifty, and toward the east two hundred and fifty, and toward the west two hundred and fifty.

¹⁸ And the remainder of that area running lengthwise along the terumat hakodesh shall measure ten alafim [cubits] eastward, and ten alafim westward; and the increase thereof shall be for lechem unto them that serve the Ir.

¹⁹ And they that serve the Ir shall serve it out of all the Shivtei Yisroel.
