13 This is my third trip to your city and community. As the Scripture says, “Every charge must be confirmed by two or three witnesses.”^{[a] 2} As I said before on my second visit, I say now again while absent. Consider this an advance warning, if you wish, to those of you still caught up in your old sins and to all the rest as well: when I come the next time, I will not spare anyone who is out of order.
