'Excusing' in the Bible

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.

Ye think all this time that we are excusing ourselves unto you. In the sight of God speak we in Christ. But all things, beloved, are for your edifying.
