Warning Against Pride and Boasting

1 Corinthians 4:6-7

And these things, brethren, I did transfer to myself and to Apollos because of you, that in us ye may learn not to think above that which hath been written, that ye may not be puffed up one for one against the other,

for who doth make thee to differ? and what hast thou, that thou didst not receive? and if thou didst also receive, why dost thou glory as not having received?
