'Covered' in the Bible

Then Mordecai returned to the gate of the king, and Haman rushed to his house mournful and with his head covered.

And the king returned from the palace garden to the {banquet hall}, [where] Haman [was] lying prostrate on the couch that Esther [was] on, and the king said, "Will he also molest the queen with me in the house?" As the words went from the king's mouth they covered Haman's face.
