The imprint of an official's signet ring (v. 10) was the equivalent of his signature in ancient times (cf. Gen. 41:42; Esth. 8:2, 8, 10). Ahasuerus gave permission to Haman to confiscate the Jews' wealth and to put them to death (v. 11). The words "to destroy, to kill, and to annihilate"(v. 13) probably translate the legal formula used in the decree that would have been as specific as possible. Probably the government officials and army were those who were to seize the Jews' property (v. 13) and then send some of it up the line to Haman.
"There is a skillful use of contrast in the last sentence of the chapter. While the collaborators celebrate, the city of Susa is aghast. The author is sensitive to popular reactions and notes that the ordinary citizen asked himself what lay behind such a drastic scene."66
