What does Ezekiel 48:15 mean?

The land left over, 5,000 cubits wide and 25,000 cubits long, isn’t sacred. It’s for the city, for farming, and for people to live in. The city sits right in the middle of it. Ezekiel 48:15 - Modern Text Bible

(The remaining land is for everyday use—homes, fields, and the city itself.)
