1 Corinthians 4:6-7

4:6 I have applied these things to myself and Apollos because of you, brothers and sisters, so that through us you may learn “not to go beyond what is written,” so that none of you will be puffed up in favor of the one against the other. 4:7 For who concedes you any superiority? What do you have that you did not receive? And if you received it, why do you boast as though you did not?
