Galatians 1:16-20

to reveal His Son in me, that I might preach Him among the Gentiles, I did not immediately confer with flesh and blood, nor did I go up to Jerusalem to those who were apostles before me; but I went to Arabia, and returned again to Damascus. Then after three years I went up to Jerusalem to see Peter, and remained with him fifteen days. But I saw none of the other apostles except James, the Lord’s brother. (Now concerning the things which I write to you, indeed, before God, I do not lie.)
