Jamieson, Fausset & Brown, on Esth 4:11

“All the king’s servants, and all the provinces that are under his dominion, know, that whosoever, whether man or woman, cometh into the king’s inner court, who is not called for, is immediately to be put to death without any delay: except the king shall hold out the golden sceptre to him, in token of clemency, that so he may live. How then can I go in to the king, who for these thirty days now have not been called unto him?”

“whosoever, whether man or woman, shall come unto the king into the inner court, who is not called--The Persian kings surrounded themselves with an almost impassable circle of forms. The law alluded to was first enacted by Deioces, king of Media, and afterwards, when the empires were united, adopted by the Persians, that all business should be transacted and petitions transmitted to the king through his ministers. Although the restriction was not intended, of course, to apply to the queen, yet from the strict and inflexible character of the Persian laws and the extreme desire to exalt the majesty of the sovereign, even his favorite wife had not the privilege of entree, except by special favor and indulgence. Esther was suffering from the severity of this law; and as, from not being admitted for a whole month to the king's presence, she had reason to fear that the royal affections had become alienated from her, she had little hope of serving her country's cause in this awful emergency.”
