2 Corinthians 13:1-3; 2 Corinthians 13:10

1 This is the third time I am coming to you. At the mouth of two witnesses or three shall every word established.

2 I have said beforehand, and I do say beforehand, as when I was present the second time, so now, being absent, to them that have sinned heretofore, and to all the rest, that, if I come again, I will not spare;

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

10 For this cause I write these things while absent, that I may not when present deal sharply, according to the authority which the Lord gave me for building up, and not for casting down.
