Galatians 2:1-5 Then fourteen years after I went up again to Jerusalem with Barnabas, and took Titus with me also. And I went up by revelation and communicated unto them that gospel which I preach among the Gentiles, but privately to them which were of reputation, lest by any means I should run, or had run, in vain. But neither Titus, who was with me, being a Greek, was compelled to be circumcised: And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage: To whom we gave place by subjection, no, not for an hour; that the truth of the gospel might continue with you.
‘Then fourteen years after I went up again to Jerusalem with Barnabas.’ Paul’s next trip to Jerusalem was 14 years after his visit of Galatians 2:16-18. Whether this refers to the visit of Acts 11:30 or 15:4 is not clear.
‘Revelation’ [Greek: apokalupsis] to unveil or uncover. It implies the lifting up of a curtain so that all can see alike what is uncovered. When used of writing, it means to reveal or make clear (1:12; Eph. 3:3); when used of a person, it denotes visible presence (Rev. 1:1; 2Thess. 1:7; 1Pet. 1:7, 13).
‘Communicated’ [Greek: anatithemi] declared. This suggests that it was at the general conference in Acts 15:1-41 when Paul, Barnabas, and others went up to settle doctrinal disputes in the early congregations, and not to take collections to the poor saints, as in Acts 20:21. When taking collections to Jerusalem he did not stay any length of time or discuss doctrines, as far as we know.
‘Privately to them which were of reputation, lest by any means I should run, or had run, in vain.’ This suggests that Paul had some private conferences with the apostles previous to going before the public with his declaration of the gospel to the Gentiles (Acts 15:4, 12). He did this lest he finds himself labouring in vain (2:2), and also to keep spies from knowing about his Gentile program to keep down trouble (2:4-5). After these conferences, not even circumcision was demanded of Titus (2:3).
‘Unawares’ [Greek: pareisaktos] brought in stealthily.
