The answer is: Assassinate the king

Esther 2:21

In the vibrant tapestry of the Book of Esther, Bigthan and Teresh step into the plot as two royal guards with a nefarious scheme: to assassinate King Xerxes. Their silky whispers of betrayal seem like a subplot from an intense drama, yet it highlights the pivotal role of intrigue and loyalty in the Persian court. Esther 2:21 points out their treachery, and how, if left unchecked, their plot could have torn the fabric of loyalty to shreds!

What’s fascinating is how this moment reflects a larger theme of providence intertwined with the actions of seemingly ordinary people. Isn’t it remarkable how the destiny of an entire nation hinged on the bravery of a young woman, who, risking tradition and her own safety, ultimately set things right? It makes you wonder just how many lives have been changed by those brave enough to stand against fear and challenge the status quo.

Also, let's appreciate the irony: here were two guards meant to protect, whose betrayal could have turned into open rebellion. History echoes of similar narratives; just look at Roman Emperor Julius Caesar's famed caution of “Et tu, Brute?” when betrayed by his close associate, Brutus.

In literature, such twists entail thrilling climaxes, yet here they carry crucial lessons about faithfulness, courage, and how every individual—regardless of their status—can shape their story and the world around them. Ain't that a significant takeaway?
