Philip Sidney, letter to Edward Molyneux (May 31, 1578):
Few woordes are beste. My lettres to my Father have come to the eys of some. Neither can I condemne
any but yow for it. If it be so yow have plaide the very knave with me; and so I will make yow know if I have good proofe of it. But that for so muche as is past. For that is to come, I assure yow before God, that if ever I know yow do so muche as reede any lettre I wryte to my Father, without his commandement, or my consente, I will thruste my Dagger into yow. And truste to it, for I speake it in earnest. In the meane time farwell.
