1:17 Neither went I up to Jerusalem to them who were apostles before me. He did not seek those who were apostles before him at Jerusalem to be taught.
I went into Arabia. This is the only place where this fact is mentioned. Like Moses and Elijah, he spent a season, perhaps for reflection, communion with God, and preparation, amid the Arabian solitudes. He then
returned again to Damascus. Here he probably did his first preaching (Ac 9:20-23). Arabia lay south and east of Palestine, extending to the vicinity of Damascus.
1:17 Neither did I go up to Jerusalem - The residence of the apostles. But I immediately went again into Arabia, and returned again to Damascus - He presupposes the journey to Damascus, in which he was converted, as being known to them all.
1:15-24 St. Paul was wonderfully brought to the knowledge and faith of Christ. All who are savingly converted, are called by the grace of God; their conversion is wrought by his power and grace working in them. It will but little avail us to have Christ revealed to us, if he is not also revealed in us. He instantly prepared to obey, without hesitating as to his worldly interest, credit, ease, or life itself. And what matter of thanksgiving and joy is it to the churches of Christ, when they hear of such instances to the praise of the glory of his grace, whether they have ever seen them or not! They glorify God for his power and mercy in saving such persons, and for all the service to his people and cause that is done, and may be further expected from them.
