Esther 4:10-11

Then Esther told Hathach to tell Mordecai, “All the royal officers and people of the royal states know that no man or woman may go to the king in the inner courtyard without being called. There is only one law about this: Anyone who enters must be put to death unless the king holds out his gold scepter. Then that person may live. And I have not been called to go to the king for thirty days.”
