'Proof' in the Bible

And with this confidence, I was wanting to come to you previously, in order that you may have a second proof of my goodwill,

For to this end also did I write, that I might know the proof of you, whether ye be obedient in all things.

how that in much proof of affliction the abundance of their joy and their deep poverty abounded unto the riches of their liberality.

And we send with them our brother, of whose zeal we have had frequent proof in many matters, and who is now more zealous than ever through the strong confidence which he has in you.

Wherefore shew ye to them, and before the churches, the proof of your love, and of our boasting on your behalf.

They will glorify God for your obedience to the confession of the gospel of Christ, and for your generosity in sharing with them and with others through the proof provided by this service.

Since ye seek a proof of Christ speaking in me, which to you-ward is not weak, but is mighty in you.
