Galatians 1:17-19

Verse 17

Neither went I up to Jerusalem - The aim of the apostle is to show that he had his call so immediately and pointedly from God himself, that he had no need of the concurrence even of the apostles, being appointed by the same authority, and fitted to the work by the same grace and Spirit, as they were.

But I went into Arabia - That part of Arabia which was contiguous to Damascus, over which Aretas was then king. Of this journey into Arabia we have no other account. As St. Luke was not then with him, it is not inserted in the Acts of the Apostles. See introduction to this epistle. Jerusalem was the stated residence of the apostles; and, when all the other believers were scattered throughout the regions of Judea and Samaria, we find the apostles still remaining, unmolested, at Jerusalem! Act 8:1.
Verse 18

After three years I went up to Jerusalem to see Peter - These three years may be reckoned either from the departure of Paul from Jerusalem, or from his return from Arabia to Damascus.

To see Peter - Ιστορησαι Πετρον, to become personally acquainted with Peter; for this is the proper import of the verb ἱστορειν, from which we have the word ἱστορια, history, which signifies a relation of things from personal knowledge and actual acquaintance. How far this is, now, from the sense in which we must take the word, ninety-nine of every hundred of our histories sufficiently show. They are any thing but true relations of facts and persons.

And abode with him fifteen days - It was not, therefore, to get religious knowledge from him that he paid him this visit. He knew as much of the Jewish religion as Peter did, if not more; and as to the Gospel, he received that from the same source, and had preached it three years before this.
Verse 19

James the Lord's brother - Dr. Paley observes: There were at Jerusalem two apostles, or at least two eminent members of the Church, of the name of James. This is distinctly inferred from the Acts of the Apostles, Act 12:2, where the historian relates the death of James, the brother of John; and yet, in Act 15:13-21, and in Act 21:18, he records a speech delivered by James in the assembly of the apostles and elders. In this place James, the Lord 's brother, is mentioned thus to distinguish him from James the brother of John. Some think there were three of this name: -

1. James, our Lord's brother, or cousin, as some will have it;

2. James, the son of Alphaeus; and

3. James, the son of Zebedee. But the two former names belong to the same person.
