'Covered' in the Bible

Then Mordecai returned to the king’s gate. But Haman hurried home, mourning, with his head covered.

Now when the king returned from the palace garden into the place where they were drinking wine, Haman was falling on the couch where Esther was. Then the king said, “Will he even assault the queen with me in the house?” As the word went out of the king’s mouth, they covered Haman’s face.
