Galatians 1:17
17 Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.
Gal. 1:17. "Neither went I up to Jerusalem to them which were apostles before me, but I went into Arabia and returned again to Damascus." It is probable that this was Arabia Deserta, which was that part of Arabia that lay nearest to Damascus, lying east of the land of Canaan, and reached up to the very neighborhood of Damascus. By the apostle's going from Damascus into Arabia, and returning from thence into Damascus again, it looks as if the Arabia that he went into, was that which was neighboring to this city. As Christ after his baptism withdrew into the wilderness, before he actually began to preach; so it is no improbable conjecture that Paul, after his conversion and baptism, withdrew into the deserts of Arabia, there to receive the knowledge of the gospel, by immediate revelation from Christ; and that this being done, he returned to Damascus, and after this his return that way preached Christ in their synagogues, as Acts 9:20. See Wells's Sacred Geography, part 2, p. 22, 23. This very well agrees with this context, in which the scope of the apostle is to show that he had his gospel not from men, but by revelation of Jesus Christ, as Galatians 1:12. "For I neither received it of man, neither was I taught it, but by revelation of Jesus Christ;" and verse 15, 16. "But when it pleased God who separated me from my mother's womb, and called me by his grace to reveal his Son in me, that I might preach him among the heathen, immediately I conferred not with flesh and blood."
Then follow the words of this verse that we are upon, to show how he did not confer with flesh and blood, but was taught immediately of Christ; "neither went I up to Jerusalem to them which were apostles before me, but I went into Arabia, and returned again unto Damascus." This is a desert, uninhabited country; and therefore it is the more probable that the apostle went thither for this end, and not to preach the gospel to any that dwelt there. And the inhabitants that were in Arabia Felix, under whose king, Aretas, Damascus then was, they were chiefly heathens; but preaching to the heathens was not yet begun, though there were then some Jews, that were then inhabitants of Arabia, of whom we read in Acts chap. 2; "Cretes and Arabians."
