Galatians 1:15-18

But when it was the good pleasure of God, who separated me, even from my mother’s womb, and called me through his grace, to reveal his Son in me, that I might preach him among the Gentiles; straightway I conferred not with flesh and blood: neither went I up to Jerusalem to them that were apostles before me: but I went away into Arabia; and again I returned unto Damascus. Then after three years I went up to Jerusalem to visit Cephas, and tarried with him fifteen days.
