Galatians 1:12-20 (New King James Version)

¹² For I neither received it from man, nor was I taught it, but it came through the revelation of Jesus Christ.
¹³ For you have heard of my former conduct in Judaism, how I persecuted the church of God beyond measure and tried to destroy it. ¹⁴ And I advanced in Judaism beyond many of my contemporaries in my own nation, being more exceedingly zealous for the traditions of my fathers.
¹⁵ But when it pleased God, who separated me from my mother’s womb and called me through His grace, ¹⁶ to reveal His Son in me, that I might preach Him among the Gentiles, I did not immediately confer with flesh and blood, ¹⁷ nor did I go up to Jerusalem to those who were apostles before me; but I went to Arabia, and returned again to Damascus.

¹⁸ Then after three years I went up to Jerusalem to see Peter,^[a] and remained with him fifteen days. ¹⁹ But I saw none of the other apostles except James, the Lord’s brother. ²⁰ (Now concerning the things which I write to you, indeed, before God, I do not lie.)
