We know no details concerning the identities of the assassins who tried to kill Ahasuerus or what motivated them. Extra-biblical sources have not yet clarified these matters, though the commentators love to speculate. We do know that14years later Ahasuerus did die at the hand of an assassin. [1] Mordecai"s position in the government is another evidence of God"s providential preparation to deliver His people. "Gallows" ( Esther 2:23; cf. Esther 5:14; Esther 7:10) is literally "tree."[source]
"Rather than being hanged by the neck on a modern-type gallows, the men were probably impaled on a stake or post (cf. Ezra 6:11). This was not an unusual method of execution in the Persian Empire. Darius, Xerxes" father, was known to have once impaled3 ,000 men." [2][source]
Ahasuerus was careful to record the name, father, and town of anyone who demonstrated particular loyalty to his throne and to reward him quickly and generously. [1][source]
"Xerxes is consumed with power yet powerless as sovereign events unfold." [4][source]
