Galatians
King James Version (KJV)

“Now the things which I write unto you, behold, before God, I lie not.”
King James Version (KJV)
1:18 Then after three years - Wherein I had given full proof of my apostleship. I went to visit Peter - To converse with him.
1:19 But other of the apostles I saw none, save James the brother (that is, the kinsman) of the Lord - Therefore when Barnabas is said to have brought him into the apostles, #Acts 9:27|, only St. Peter and St James are meant.
Ga 1:20 Behold, before God, I lie not. This statement, an important one in view of the declarations of the Judaizers, Paul makes very solemnly.
