Esther 6:7 - Joseph Benson’s Commentary on the Old and New Testaments

Haman answered, Let the royal apparel, &c. Concluding he himself was the favourite intended, he prescribes the highest instances of honour that could for once be bestowed upon a subject; nay, he names honours too great to be conferred on any subject. Which the king useth to wear, &c. Namely, the king's outward garment, which was made of purple, interwoven with gold, as Justin and Curtius relate. To form a notion of that height of pride and arrogance at which Haman, who thought all the honours he specified were designed for himself, was arrived, we may observe, that for any one to put on the royal robe without the privity and consent of the king was among the Persians accounted a capital crime. And the horse that the king rideth upon Namely, usually; which was well known, both by his excellence, and especially by his peculiar trappings and ornaments. And the crown royal which is set upon his head Upon the king's head. Thus he wished him to appear in all the pomp and grandeur of the king himself, only not to carry the sceptre, the emblem of power.
