What does Esther 4:11 mean?

'Everyone who works for the king and all the people in the provinces know that if anyone, man or woman, goes to the king in the inner court without being called, there's only one law: death. Unless the king holds out his gold scepter, that person is killed. And I haven't been called to see the king for thirty days.' Esther 4:11 - Modern Text Bible

(Esther explained the risk: approaching the king uninvited could mean death, and she hadn't been summoned in a month.)
