Esther, the last of the historical books, contains an early example of Jewish persecution. Esther, a Jewess, is chosen as the new queen for Ahasuerus, the king of Persia. Her uncle Mordecai has incurred the enmity of Haman, the evil court favorite, and so brought the threat of death to his people. Esther, through her position, is able to avert the tragedy and save her people.

Esther 4

4:16 Go, gather together all the Jews that are present in Shushan, and fast ye for me, and neither eat nor drink three days, night or day: I also and my maidens will fast likewise; and so will I go in unto the king, which is not according to the law: and if I perish, I perish.
