“I told you before, and foretell you, as if I were present, the second time; and being absent now I write to them which heretofore have sinned, and to all other, that, if I come again, I will not spare:”
King James Version (KJV)
13:2 All the rest - Who have since then sinned in any of these kinds. I will not spare - I will severely punish them.
2Co 13:2 I told you before, etc. The Revised Version makes the meaning plain: "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". As he told them, when there the second time, so now he writes that when he comes again he will not spare offenders.
