2 Corinthians 13:3

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

seeing that you seek a proof of Christ who speaks in me; who toward you is not weak, but is powerful in you.

seeing that ye seek a proof of Christ that speaketh in me; who to you-ward is not weak, but is powerful in you:

since a proof ye seek of the Christ speaking in me, who to you is not infirm, but is powerful in you,

since you are demanding proof that Christ is speaking through me. He is not weak in dealing with you, but is powerful among you.
