Not even those who are circumcised keep the law, yet they want you to be circumcised that they may boast about your circumcision in the flesh.
NIV
For even the circumcised [Jews] themselves do not [really] keep the Law, but they want to have you circumcised in order that they may glory in your flesh (your subjection to external rites).
AMP
For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh.
KJV
Those who want to impress others by means of the flesh are trying to compel you to be circumcised. The only reason they do this is to avoid being persecuted for the cross of Christ.
NIV
Those who want to make a good impression and a fine show in the flesh would try to compel you to receive circumcision, simply so that they may escape being persecuted for allegiance to the cross of Christ (the Messiah, the Anointed One).

KJV
For God, who was at work in Peter as an apostle to the Jews, was also at work in me as an apostle to the Gentiles.

And the law is not of faith: but, The man that doeth them shall live in them.

NIV
But on the contrary, when they [really] saw that I had been entrusted [to carry] the Gospel to the uncircumcised [Gentiles, just as definitely] as Peter had been entrusted [to proclaim] the Gospel to the circumcised [Jews, they were agreeable]AMP
But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
