Paul then heads to Corinth (for a map, read back a bit). Here trouble arises again, but God encourages him to not stop. He sees two new converts that are a part of the story from here on out (Aquila and Priscilla). After Corinth, Paul and Silas start to head back to Antioch, but first he cuts his hair for a vow. This was likely a vow like a Nazarite vow, where one does not cut their hair to commit themselves to service of the Lord. Samson was the most famous Nazarite, even if he was terrible at the vow. He goes into Ephesus to sail out from there and plants a church. They ask him to stay, but he declines and promises to return if he may. A character named Apollos teaches there and begins to build the church after learning from Priscilla and Aquila the ways of God. God’s church is being built!
In the meantime, Paul heads back to Antioch and works there for a while.
