Origen

“ What need is there to quote all the princes and private persons in Scripture history who fared well or ill according as they obeyed or despised the words of the prophets? If we refer to those who were unhappy because they were childless, but who, after offering prayers to the Creator of all, became fathers and mothers, let any one read the accounts of Abraham and Sarah, to whom at an advanced age was born Isaac, the father of the whole Jewish nation: and there are other instances of the same thing. ”

“ It is related of the priestess of Apollo, that she at times allowed herself to be influenced in her answers by bribes; but our prophets were admired for their plain truthfulness, not only by their contemporaries, but also by those who lived in later times. For through the commands pronounced by the prophets cities were founded, men were cured, and plagues were stayed. ”
