Esther 3:7

And this house was brought to completion on the third day of the month Adar; it was the sixth year of the reign of King Darius.

For Haman the son of Hammedatha, the Agagite, the adversary of all the Jews, had devised against the Jews to cause them to perish and had cast Pur, that is the lot, to throw them into confusion and cause them to perish.

But when it came before the king, he said by letter that his evil scheme, which he had devised against the Jews, should return on his own head and that he and his sons should be hanged on the gallows.
