Esther 1:2
“That in those days, when the king Ahasuerus sat on the throne of his kingdom, which was in Shushan the palace,”
KJV
Read in Esther 1Meaning
The verse narrows the narrative from the size of the empire to the seat of royal authority. Susa becomes the place where private choices are converted into public policy, giving the palace setting continuing importance throughout the book.
