'Wherefore' 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 Esther calleth to Hatach, of the eunuchs of the king, whom he hath stationed before her, and giveth him a charge for Mordecai, to know what this is, and wherefore this is.
