Galatians 1:16

14And profited in the Jews’ religion above many my equals in mine own nation, being more exceedingly zealous of the traditions of my fathers.

15But when it pleased God, who separated me from my mother’s womb, and called me by his grace,

16To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:

17Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.

18Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days.
