2 Chronicles 6:42 - Matthew Poole's English Annotations on the Holy Bible

Of thine anointed, i.e. of me, who by thy command and appointment was anointed the king and ruler of thy people: do not deny my present requests, nor send me back from the throne of thy grace with a sad heart and dejected countenance. The mercies of David thy servant, i.e. those which thou hast promised to David and to his house for ever.
