Acts 18:20-23
18:20 When they asked him to stay longer, he would not consent,
18:21 but said farewell to them and added, “I will come back to you again if God wills.” Then he set sail from Ephesus,
18:22 and when he arrived at Caesarea, he went up and greeted the church at Jerusalem and then went down to Antioch.
18:23 After he spent some time there, Paul left and went through the region of Galatia and Phrygia, strengthening all the disciples.
