Biblical ladies and HBICs » Esther, queen of Persia
From royal concubine to queen, married to king Serses of Persia, she kept hidden her true jew identity and saved her husband’s life and the empire several times with her wisdom and cleverness. When a minister plotted to have all the Jews killed and extirpated throughout the Persian empire, she fasted three days, then came unto the king uncalled by him - a crime punished by death - and revealed she was herself jewish, convincing Serses to grant her people life and freedom. She had her life spared. Her courage and legacy were so important that she has a whole book of the Bible dedicated to her, the Book of Esther, and the jewish feast of Purim.
"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."
