The Persian Empire stretched from Ethiopia to India and consisted of one hundred twenty seven provinces with varied languages and customs. One of the ways the king of Persia managed communication in his kingdom was to make his laws irrevocable. Once a decree was sent out, there was no turning back. In order to avoid any confusion or mistrust among his magistrates, the king could not repeal a law once it was established. This meant that Haman the Agagites’s order to kill all the Jews would still be carried out even though he had been hanged on the gallows he had built for Esther’s uncle, Mordecai.
King Ahasuerus’ remedy for the situation was to allow the Jews to defend themselves. It says in Esther 8:11, “Whereas the king granted the Jews which were in every city to gather themselves together, and to stand for their life, to destroy, to slay, and to cause to perish, all the power of the people and providence that would assault them, both the little ones and women, and to take the spoil of them for a prey.” It might seem like self-defense was a natural solution to their problem, but the Jews status (exiled) in the kingdom of Persia prevented them from fighting against their captors.
An unintended, but advantageous outcome of the Jews obtaining permission to fight against the people that wanted to kill them was the destruction of the Amalekites. God had commanded Israel’s king, Saul to utterly destroy the people of Amalek hundreds of years earlier (1 Samuel 15:3), but Saul disobeyed and let some of the household of Agag, the king of Amalek, escape. Due to his mistake, Haman the Agagite was able to threaten the Jews existence. But, after the tables were turned, the Jews finally accomplished a long overdue objective, the elimination of their fiercest enemy.
