Rabanus Maurus : Moreover, what follows next—"And the king's edict was published in Shushan"— means that the domain of the heavenly king rules over and governs the entire world: "everything has been placed under his jurisdiction, and there is no one who can resist his will" (Esther 13); and our mundane ambitions are laid low by his power. So it makes sense that according to the text the king's edict was also published in Shushan, since "Shushan" means riding or conveying. In the end, the arrogance of the world is bested by the power of God; which is why the Savior says to his disciples in the Gospel: "in the world, you will face repression; but take heart, for I have conquered the world" (John 16). — Commentary on Esther
