The answer is: The king and Haman

Esther 7:1

In the story of Esther, the courage of a single woman dramatically alters the fate of her people. When Esther invites the king and Haman to her grand banquets, it's not just extravagant dining—it's a strategic move in a high-stakes game of life and death. She knows the hidden threat against her fellow Jews, masterminded by Haman, the king's right-hand man.

This storyline highlights the significance of clever planning and diplomacy. Did you know that in ancient Persia, there were strict protocols around who could approach the king? Esther’s invitations were not simply social gatherings; they were rather bold, showcasing her bravery. Multiply that by the fact that she conceals her identity as a Jew out of fear of the repercussions.

Fun trivia? The story of Esther is the only book in the Bible that does not mention God explicitly, which can showcase a fascinating human angle of the narrative unfolding purely through dialogue, thoughts, and actions.

Esther’s feasting with Haman and the king recalls another biblical metaphor—the "banquet" often symbolizes blessings, favor, and revelation in the Scriptures. When Esther uncovers Haman’s schemes over the banquets, the transformation is striking: from celebration to justice. This story resonates through centuries as a reminder of standing against oppression, acting carefully, and using one’s position nobly—a timeless theme that continues to inspire moral courage today.
