'Proved' 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.

And we have sent with them our brother whom we have often proved to be of diligent zeal in many things, and now more diligently zealous through the great confidence he has as to you.
