Behold, all ye yourselves have seen it; Why then are ye thus altogether vain?
Behold, all of you have seen it yourselves; why then have you become altogether vain [cherishing foolish notions]?
Behold, all ye yourselves have seen it; Why then are ye become altogether vain?
Look, those of you who recognize this— why then this empty talk?
Behold, you know all this, and so why do you speak vain things without a reason?
