'Throne' in the Bible

In those days as King Ahasuerus was sitting on the throne of his kingdom, which [was] in the citadel of Susa,

And it happened, on the third day, and Esther put on royal clothes, and she stood in the inner courtyard of the {king's palace}, opposite the {king's palace}; the king [was] sitting on his royal throne in the {throne room} opposite the doorway of the palace.
