William Shakespeare: King Lear, Act III, Scene III

Alack, alack, Edmund, I like not this unnatural dealing. When I desire their leave that I might pity him, they took from me the use of mine own house; charged me, on pain of their perpetual displeasure, neither to speak of him, entreat for him, nor any way sustain him.

Go to; say you nothing. There's a division betwixt the dukes; and a worse matter than that: I have received a letter this night; 'tis dangerous to be spoken; I have locked the letter in my closet: these injuries the king now bears will be revenged home; there's part of a power already footed: we must incline to the king. I will seek him, and privily relieve him: go you and maintain talk with the duke, that my charity be not of him perceived: if he ask for me. I am ill, and gone to bed. Though I die for it, as no less is threatened me, the king my old master must be relieved. There is some strange thing toward, Edmund; pray you, be careful.
