'Set apart' in the Bible

This holy donation will be set apart for the priests alone. It will be 8⅓ miles long on the northern side, 3⅓ miles wide on the western side, 3⅓ miles wide on the eastern side, and 8⅓ miles long on the southern side. The Lord’s sanctuary will be in the middle of it.

The entire donation will be 8⅓ miles by 8⅓ miles; you are to set apart the holy donation along with the city property as a square area.
