1 Corinthians 4:6-7

WNT(i) 6 In writing this much, brethren, with special reference to Apollos and myself, I have done so for your sakes, in order to teach you by our example what those words mean, which say, "Nothing beyond what is written!" --so that you may cease to take sides in boastful rivalry, for one teacher against another. 7 Why, who gives you your superiority, my brother? Or what have you that you did not receive? And if you really did receive it, why boast as if this were not so?
