It's interesting how the wife of Haman; Zeresh and his wise men knew that Haman was going to fall utterly if he is going against a Jew. The gentiles in the old testament knew about the Jews and their God as well as the mighty deeds he did for them. If the jews could not be destroyed because of their connection with God, we as His children, if He be for us God, who can be against us? (Esther 6:15)
