C. F. Keil and Franz Delitzsch on Esther 8:1

Est 8:1

By the execution of Haman, his property was confiscated, and the king decreed that the house of the Jews’ enemy should be given to Esther. The “house of Haman” undoubtedly means the house with all that pertained to it. “And Mordochai came before the king, for Esther had told him what he was to her,” viz., her kinsman and foster-father, Est 2:7. This information effected Mordochai’s appearance before the king, i.e., his reception into the number of the high dignitaries who beheld the face of the king, i.e., were allowed personal access to him; comp. Est 1:10, Est 1:14; Est 7:9.
