Galatians 1:20 (KJV)

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

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

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

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

But other of the apostles saw I none, save James the Lord's brother.

Afterwards I came into the regions of Syria and Cilicia;

And was unknown by face unto the churches of Judaea which were in Christ:

But they had heard only, That he which persecuted us in times past now preacheth the faith which once he destroyed.

And they glorified God in me.
