John Gill Commentary Esther 8:1

"On that day did the king Ahasuerus give the house of Haman the Jews` enemy unto Esther the queen. And Mordecai came before the king; for Esther had told what he was unto her." — Esther 8:1 (ASV)

On that day did the King, Ahasuerus, give the house of Haman, the Jews' enemy, to Esther the queen That, and all the goods in it, and estate belonging to it; which being confiscated to the king, he gave to Esther, who would have been the sufferer, had his scheme taken place; so the Targum adds, ``and the men of his house, and all his treasures, and all his riches:''

and Mordecai came before the king ; was introduced into his presence, became one of his privy counsellors, one of those that saw the king's face, and sat first in the kingdom, (Esther 1:14)

for Esther has told what he was to her ; what relation he stood in to her; her uncle, according to the Vulgate Latin version, and so Aben Ezra and Josephus, but wrongly, for she was his uncle's daughter; so that they were brother's children, or own cousins, see (Esther 2:7) .
