Galatians 1:17-18; Galatians 2:1

17 Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus. 18 Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days.
1 Then fourteen years after I went up again to Jerusalem with Barnabas, and took Titus with me also.
