Paul circumcises Timothy, not because he believes circumcision is required (he doesn't), but because he is worried about what Timothy's Jewish neighbors might think. It was a politically correct circumcision.
Then the Holy Ghost prohibited Paul from preaching in Asia and Bithynia. So he went to Macedonia instead - since he had a dream about a man from Macedonia who said, "Come and help us."
And at the end of the episode, Paul shaves his head because he had taken a vow. Was this the Nazarite vow as described in Numbers 6?
