1 Corinthians 1:11

But seeing that whoso is blamed is unabashed so long as he hath no witnesses, observe how, not permitting them to deny the fact, he adduces some to bear witness. "For it hath been signified unto me concerning you, my brethren, by them which are of the household of Chloe." Neither did he say this at the very beginning, but first he brought forward his charge; as one who put confidence in his informants. Because, had it not been so, he would not have found fault: for Paul was not a person to believe lightly. Neither then did he immediately say, "it hath been signified." Consider also his prudence in not speaking of any distinct person, but of the entire family; so as not to make them hostile towards the informer: for in this way he both protects him, and fearlessly opens the accusation. For he had an eye to the benefit not of the one side only, but of the other also. Wherefore he saith not, "It hath been declared to me by certain," but he indicates also the household, lest they might suppose that he was inventing. What was "declared?" "That there are contentions among you." Thus, when he speaks, he relies upon the informants.
