Esther 6:8

Let the royal apparel be brought which the king useth to wear, and the horse that the king rideth upon, and the crown royal which is set upon his head:

The royal apparel ... which the king useth to wear - made of purple interwoven with gold (Xenophon, 'Cyropaedia,' b. 8:, ch. 3, sec. 13; Quintus Curtius, b. 3:, ch. 3:, p. 27; Justin, 12: 3). A coat which has been on the back of a king or prince is reckoned a most honourable gift, and is given with great ceremony.

The horse that the king rideth upon. Persia was a country of horses, and the high-bred charger the king rode upon, usually brought from Armenia, remarkable for beauty and symmetry (Herodotus, b. 7:, 40; cf. also b. 3:, 106; b. 4:, 189), acquired, in the eyes of his venal subjects, a sort of sacredness from that circumstance.

And the crown royal which is set upon his head - either the royal turban, or, it may be, a tiara, with which, in state recessions, the horse's head was adorned. In the Roman triumphal processions, horses were also crowned.
