'Art' in the Bible

And the servants of the king, who are in the gate of the king, say to Mordecai, 'Wherefore art thou transgressing the command of the king?'

and Haman recounteth to Zeresh his wife, and to all his friends, all that hath met him, and his wise men say to him, and Zeresh his wife, 'If Mordecai is of the seed of the Jews, before whom thou hast begun to fall, thou art not able for him, but dost certainly fall before him.'
