Sorry bout all the Esther Questions. I'm just teaching through it and am running up against a couple of things that I hear different things on and wanted some other opinions or answers....

------The question is - Why did Mordecai ask Esther to keep her Jewishness secret? Was there a greater resentment against the Jews than other races in the Persian kingdom, or was it something to do with Haman?

Thanks!
