'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?'

For if thou altogether holdest thy peace at this time, then shall there enlargement and deliverance arise to the Jews from another place; but thou and thy father's house shall be destroyed: and who knoweth whether thou art come to the kingdom for such a time as this?

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.'
