'Unless' in the Bible

In the evening she would go into the palace and in the morning she would return to the second harem, into the care of Shaashgaz, the king's eunuch who was in charge of the mistresses. She would not go again to the king unless the king wanted her and she was called for by name.

"Every servant of the king and every person in the king's provinces knows that for any man or woman who goes to the king in the inner court without being summoned there is only one law that he be put to death unless the king holds out the golden scepter to him. Only then he will live. For these last 30 days I've not been summoned to come to the king."
