2 Corinthians 13:2

2. St. Paul now carries out his tri-personal figure by specifying his own threefold testimonies.

I told you before Literal Greek, I have fore-affirmed, and I foretell as present the second [time,] and absent now, to those having before sinned, and to the rest all, that if I come again I will not spare. The three witnesses in St. Paul’s one person are: 1. His fore-affirmation in his first epistle, 1 Corinthians 4:20; 1 Corinthians 2:0. His present epistle, which is the expression of his second intention of visit, 2 Corinthians 1:15; 2 Corinthians 3:0. His actual come again, of which he here expresses the if. Those having before sinned are the incorrigible ones who had stood all the three warnings.
