'Covered' in the Bible

And Mordecai came again to the king's gate. But Haman hasted to his house, mourning and having his head covered.

And the king returned out of the palace garden into the house of the banquet of wine, and Haman was fallen upon the couch on which Esther was. And the king said, Will he even force the queen before me in the house? The word went forth out of the king's mouth, and they covered Haman's face.
