NET

11 For see what this very thing, this sadness as God intended, has produced in you: what eagerness, what defense of yourselves, what indignation, what alarm, what longing, what deep concern, what punishment! In everything you have proved yourselves to be innocent in this matter.

Darby

11 For, behold, this same thing, your being grieved according to God, how much diligence it wrought in *you*, but [what] excusing [of yourselves], but [what] indignation, but [what] fear, but [what] ardent desire, but [what] zeal, but [what] vengeance: in every way ye have proved yourselves to be pure in the matter.

KJV

11 For behold this selfsame thing, that ye sorrowed after a godly sort, what carefulness it wrought in you, yea, [what] clearing of yourselves, yea, [what] indignation, yea, [what] fear, yea, [what] vehement desire, yea, [what] zeal, yea, [what] revenge! In all [things] ye have approved yourselves to be clear in this matter.
