Mordecai raised his orphaned niece Esther like his own daughter, teaching her wisdom and obedience. When the king sought a new queen, Mordecai knew Esther was ready. She became queen but stayed loyal to Mordecai. Later, Mordecai learned of a plot to kill all Jews and demanded Esther intervene with the king despite the risk. He told her that if she remained silent, God would save the Jews through others, but she and her family would perish. Esther obeyed Mordecai and used her position to save her people, though God could have acted through others if she did not.
