King Henry IV, Part 1

Those opposed eyes, Which like the Meteors of a troubled Heaven, All of one Nature, of one Substance bred, Did lately meete in the intestine shocke, And furious cloze of ciuill Butchery, Shall now in mutuall well-beseeming rankes March all one way, and be no more oppos'd Against Acquaintance, Kindred, and Allies.

The edge of Warre, like an ill-sheathed knife, No more shall cut his Master.
