Albert Barnes Commentary Esther 3:9

"If it please the king, let it be written that they be destroyed: and I will pay ten thousand talents of silver into the hands of those that have the charge of the [king`s] business, to bring it into the king`s treasuries." — Esther 3:9 (ASV)

Ten thousand talents of silver: According to Herodotus, the regular revenue of the Persian king consisted of 14,560 silver talents; so that, if the same talent is meant, Haman’s offer would have exceeded two-thirds of one year’s revenue (or two and a half million British pounds sterling). Another Persian subject, Pythius, once offered to present Xerxes with four million gold darics, or about four and a half pounds.
