By the time Silas and Timotheus came south from Macedonia, Paul was engrossed in this preaching of the word, arguing to the Jews that the messiah was Jesus.
Then he said to them, "When I was still with you, this is what I told you, that whatever is written about me in the law of Moses and the prophets and the psalms must be fulfilled."
He had been instructed in the Way of the Lord and he preached and taught about Jesus with ardour and accuracy, though all the baptism he knew was that of John.
