Вот, все вы и сами видели; и для чего вы столько пустословите?
You have all seen this yourselves. Why then this meaningless talk?
Behold, all of you have seen it yourselves; why then have you become altogether vain?
“Behold, all of you have seen it; Why then do you act foolishly?
But you have seen all this, yet you say all these useless things to me.
Behold, all ye yourselves have seen it; why then are ye thus altogether vain?
Surely all of you have seen it; Why then do you behave with complete nonsense?
Behold, ye yourselves have all seen [it]; and why are ye thus altogether vain?
