As we have said before, and now I say again: If anyone is preaching to you (hymas | ὑμᾶς | acc pl 2nd) a gospel at odds with the one you have already received, let him be accursed.
But even if we, or an angel from heaven, should preach a gospel at odds with the one we already preached to you (hymin | ὑμῖν | dat pl 2nd), let him be accursed.
not that there is another gospel, but there are some who are trying to confuse you (hymas | ὑμᾶς | acc pl 2nd) and want to pervert the gospel of Christ.
I am astonished that you are so quickly deserting the one who called you (hymas | ὑμᾶς | acc pl 2nd) by the grace of Christ and are turning to a different gospel —
