When Mordecai learned of the plot, he reported it to Queen Esther, and she told the king on Mordecai’s behalf.

Now when the plot was investigated and found to be so, they were both hanged on a gallows; and it was written in the Book of the Chronicles in the king’s presence.

In the twelfth year of the reign of King Ahasuerus, in the first month (the month Nisan), the (that is, the lot) was cast in Haman's presence to determine the best day and month to carry out his plot. The lot indicated the twelfth month, the month Adar.

Mordecai also gave him a copy of the text of the decree which had been issued in Susa for the Jews destruction, so that he might show Esther and explain it to her, and order her to go in to the king to seek his favor and plead with him for [the lives of] her people.

His wife Zeresh and all his friends told him, “Have them build a gallows 75 feet high. Ask the king in the morning to hang Mordecai on it. Then go to the banquet with the king and enjoy yourself.” The advice pleased Haman, so he had the gallows constructed.

Then Esther spoke again to the king and fell down at his feet and wept and implored him to avert the evil plot of Haman the Agagite and his plan which he had devised against the Jews [because the decree to annihilate the Jews was still in effect].

And he wrote in the name of king Ahasuerus, and sealed it with the king's ring, and sent letters by couriers on horseback riding on coursers, horses of blood reared in the breeding studs:

The couriers mounted on coursers and horses of blood went out, being hastened and pressed on by the king's commandment. And the decree was given at Shushan the fortress.

But when it came {to the attention of} the king, he {gave orders in writing} [that] his evil plot that he had devised against the Jews should return on his head, and they hung him and his sons on the gallows.
