but on the contrary seeing that I was intrusted with the gospel of the uncircumcision, as Peter was of the circumcision,??8 for he that operated in Peter for the apostleship of the circumcision, operated also in me for the gentiles,??9 and knowing the grace given me, James and Cephas and John, who were manifest pillars, gave to me and Barnabas the right hand of fellowship that we should go to the gentiles and they to the circumcision;

And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.

The rest of the Jewish Christians, too, joined him in this pretense so that even Barnabas was influenced to join them in their pretense.

But when I saw that they did not walk uprightly according to the truth of the gospel, I said to Peter, before them all: If you, being a Jew, live after the manner of the Gentiles, and not after the manner of the Jews, why do you compel the Gen tiles to observe Jewish customs?

And, predicting that God would consider the Gentiles right with Him by [their] faith, the Scriptures previously recorded [this promise of] the Gospel to Abraham by saying [Gen. 12:3], "All nations will receive a blessing through your descendant [i.e., Jesus]."

Now [specific] promises were made to Abraham and to his seed [i.e., descendants]. [God] did not say "seeds" [plural] as though He were referring to many persons but "seed" [singular] showing that He meant one [descendant]; [Gen. 13:15 says] "And to your seed," referring to Christ.

For it is written in the law about Abraham's two sons [Gen. 16]; one [was] by his slave woman [Hagar] and the other by the free woman, [his wife, Sarah].

What does the Scripture say about this matter? [It says, Gen. 21:10-12], "Get rid of the slave woman [Hagar], with her son [Ishmael]; for the son of the slave woman [Ishmael] will not inherit [what God promised to Abraham and his descendants], along with the son of the free woman [i.e., Isaac]."

Take on yourselves the [spiritual] burdens of one another, for in doing so you will be fulfilling Christ's law [of love, John 13:35].
