New American Standard Bible (NASB)
Galatians 1
18 Then three years later I went up to Jerusalem to become acquainted with Cephas, and stayed with him fifteen days.
19 But I did not see any other of the apostles except James, the Lord’s brother.
20 (Now in what I am writing to you, I assure you before God that I am not lying.)
21 Then I went into the regions of Syria and Cilicia.
22 I was still unknown by sight to the churches of Judea which were in Christ;
23 but only, they kept hearing, "He who once persecuted us is now preaching the faith which he once tried to destroy."
24 And they were glorifying God because of me.
Galatians 2
1 Then after an interval of fourteen years I went up again to Jerusalem with Barnabas, taking Titus along also.
2 It was because of a revelation that I went up; and I submitted to them the gospel which I preach among the Gentiles, but I did so in private to those who were of reputation, for fear that I might be running, or had run, in vain.
3 But not even Titus, who was with me, though he was a Greek, was compelled to be circumcised.
4 But it was because of the false brethren secretly brought in, who had sneaked in to spy out our liberty which we have in Christ Jesus, in order to bring us into bondage.
