What does Ezekiel 21:23 mean?

But to the people in Jerusalem, it’ll just look like another false alarm. They swore oaths to their allies, thinking they’d be safe. But the enemy will remind them of their guilt and capture them anyway. Ezekiel 21:23 - Modern Text Bible

(The people of Jerusalem think they’re protected by their alliances, but their past actions will catch up with them, and they’ll be taken by surprise.)
