The answer is: The king and Haman

Esther 7:1

Queen Esther's strategic invitations to her banquets serve as a masterclass in diplomacy and courage. By inviting both King Ahasuerus and Haman, Esther took significant risks, showing her adeptness at using her position for a greater purpose. Let's take a moment to explore the background here – it's a tale nestled in the heart of adversity for the Jewish people in Persia.

Esther herself embodies courage and wit. Rising from obscurity as a young Jewish woman to Queen, she stepped into a role that required not only beauty but persuasion and bravery. Her calculated banqueting is reminiscent of traditional Jewish meals that often serve as a coming-together - sharing ideas, traditions, and affairs. In ancient cultures, food has been an important part of family and political protocols. Host the king and his closest advisor at a banquet? That's *adding the spice* to politics!

On her second dinner with the king, pieces of the puzzle began to unfold, resulting in her brave revelation of Haman's plot. This brings to mind the biblical theme of reversal—think about how the mighty often tumble over their own schemes, portraying justice rolling out in unexpected ways.

Additionally, Esther's story echoes resounding themes of intervention. The curious twist in her find-the-king, speak-your-truth! tale still resonates today with stories like Joseph standing before Pharoah or Daniel standing firm before Babylonian royalty. Here’s a powerful reminder that standing in one’s truth and paving avenues—even banquets—of dialogue can change the course of not just individual lives but entire cultures.
