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

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

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

But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry.

But ye know the proof of him, that, as a son with the father, he hath served with me in the gospel.
