Galatians 1:16-18 NIV

[16] to reveal his Son in me so that I might preach him among the Gentiles, my immediate response was not to consult any human being. [17] I did not go up to Jerusalem to see those who were apostles before I was, but I went into Arabia. Later I returned to Damascus. [18] Then after three years, I went up to Jerusalem to get acquainted with Cephas and stayed with him fifteen days.
