What does Ezekiel 46:9 mean?

When the people come to worship at the appointed festivals, anyone who enters through the north gate should leave through the south gate, and anyone who enters through the south gate should leave through the north. No one should go back out the same way they came in. Everyone should leave through the opposite gate. Ezekiel 46:9 - Modern Text Bible

(God instructs the people to exit by a different gate than they entered, symbolizing a change or transformation through worship.)
