KJV:
I am become a fool in glorying; ye have compelled me: for I ought to have been commended of you: for in nothing am I behind the very chiefest apostles, though I be nothing.
NASB:
I have become foolish; you yourselves compelled me. Actually I should have been commended by you, for in no respect was I inferior to the most eminent apostles, even though I am a nobody.
KJV:
And I will very gladly spend and be spent for you; though the more abundantly I love you, the less I be loved.
NASB:
I will most gladly spend and be expended for your souls. If I love you more, am I to be loved less?
KJV:
Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
NASB:
Test yourselves to see if you are in the faith; examine yourselves! Or do you not recognize this about yourselves, that Jesus Christ is in you-- unless indeed you fail the test?
KJV:
Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
NASB:
which is really not another; only there are some who are disturbing you and want to distort the gospel of Christ.
KJV:
As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
NASB:
As we have said before, so I say again now, if any man is preaching to you a gospel contrary to what you received, he is to be accursed!
KJV:
For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ.
NASB:
For am I now seeking the favor of men, or of God? Or am I striving to please men? If I were still trying to please men, I would not be a bond-servant of Christ.
KJV:
But when I saw that they walked not uprightly according to the truth of the gospel, I said unto Peter before them all, If thou, being a Jew, livest after the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews?
NASB:
But when I saw that they were not straightforward about the truth of the gospel, I said to Cephas in the presence of all, "If you, being a Jew, live like the Gentiles and not like the Jews, how is it that you compel the Gentiles to live like Jews?
