'Capital' in the Bible

in those days as King Ahasuerus sat on his royal throne which was at the citadel in Susa,

When these days were completed, the king gave a banquet lasting seven days for all the people who were present at the citadel in Susa, from the greatest to the least, in the court of the garden of the king’s palace.

Let the king appoint overseers in all the provinces of his kingdom that they may gather every beautiful young virgin to the citadel of Susa, to the harem, into the custody of Hegai, the king’s eunuch, who is in charge of the women; and let their cosmetics be given them.

Now there was at the citadel in Susa a Jew whose name was Mordecai, the son of Jair, the son of Shimei, the son of Kish, a Benjamite,

So it came about when the command and decree of the king were heard and many young ladies were gathered to the citadel of Susa into the custody of Hegai, that Esther was taken to the king’s palace into the custody of Hegai, who was in charge of the women.

The couriers went out impelled by the king’s command while the decree was issued at the citadel in Susa; and while the king and Haman sat down to drink, the city of Susa was in confusion.

The couriers, hastened and impelled by the king’s command, went out, riding on the royal steeds; and the decree was given out at the citadel in Susa.

At the citadel in Susa the Jews killed and destroyed five hundred men,

On that day the number of those who were killed at the citadel in Susa was reported to the king.

The king said to Queen Esther, “The Jews have killed and destroyed five hundred men and the ten sons of Haman at the citadel in Susa. What then have they done in the rest of the king’s provinces! Now what is your petition? It shall even be granted you. And what is your further request? It shall also be done.”
