Galatians
King James Version (KJV)

“Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.”
King James Version (KJV)
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.
Ga 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.
