For the Jews it was a time of light and gladness, of joy and honor.
It was but a few days ago that we had Mordecai in sackcloth and all the Jews in sorrow; but here is a blessed change, Mordecai in purple and all the Jews in joy. See Psa 30:5, Psa 30:11, Psa 30:12. 1. Mordecai in purple, Est 8:15.

MORDECAI'S HONORS, AND THE JEWS' JOY. (Est 8:15-17) Mordecai went out . . . in royal apparel--He was invested with the khelaat of official honor. A dress of blue and white was held in great estimation among the Persians; so that Mordecai, whom the king delighted to honor, was in fact arrayed in the royal dress and insignia.
