2 Corinthians 13:2-3

ABU(i) 2 I have before said, and now say beforehand, as when present the second time, so also now when absent, to those who heretofore have sinned, and to all the rest, that if I come again I will not spare; 3 since ye seek a proof of Christ speaking in me, who toward you is not weak, but is mighty in you.
