Esther 7:8 And the king returned from the palace garden to the place where they were drinking wine, as Haman was falling on the couch where Esther was. And the king said, “Will he even assault the queen in my presence, in my own house?” As the word left the mouth of the king, they covered Haman’s face.
When the king returned, he saw Haman violating his wife’s space. Think about it: How big is a couch? Yes, this was the royal palace, but a couch is a couch. If Queen Esther was fully on the couch and Haman was falling on it then, even if somehow he was not touching her, he had officially gone too far.
Thus, now the king had even more incentive to do away with Haman. Shocked and filled with indignation, the king asked aloud a rhetorical question. In the king’s mind, Haman had just proven everything Esther had claimed. However, just as the king had finished speaking, the attendants grabbed Haman and covered his face.
