That such a slave as this should wear a sword,
Who wears no honesty.
– William Shakespeare
King Lear, Act 2, Scene 2. Kent is angry because a dishonest lowlife like Oswald should wear a sword like a gentleman. He believes that a man who wears a sword should be an honorable knight. For a rogue like the scheming Goneril’s slave Oswald to wear one means there is no honesty in the world and it is turned topsy turvy, Kent feels.
