Adam Clarke, on Esth 8:1

“On that day king Assuerus gave the house of Aman, the Jews’ enemy, to queen Esther, and Mardochai came in before the king. For Esther had confessed to him that he was her uncle.”

“The king - give the house of Haman - As Haman was found guilty of treasonable practices against the peace and prosperity of the king and his empire, his life was forfeited and his goods confiscated. And as Mordecai had been the means of preserving the king's life, and was the principal object of Haman's malice, it was but just to confer his property upon him, as well as his dignity and office, as Mordecai was found deserving of the former, and fit to discharge the duties of the latter.”
