At Ephesus, Paul parted from Priscilla and Aquila.

Acts 18:18-21

18 Paul stayed on with the believers in Corinth for ◄many days/some time►. Then he left the believers there, and went with Priscilla and her husband Aquila. They went down to Cenchrea, a port city. There Paul had his head shaved {someone shave his head} in order to partially complete a vow that he had taken. Then they got on a ship and sailed for Syria province. 19 They arrived at Ephesus city, and Priscilla and Aquila stayed there.

Before Paul left Ephesus, he entered the Jewish meeting place and lectured to the Jews. 20 They asked him to stay longer, but he refused. 21 But, as he left, he told them, “I will come back, if God wills/desires me to do that.” Then, because he wanted to be in Jerusalem to finish completing his vow, he got on a ship that sailed from Ephesus.
