Paul finishes up his second missionary journey in v. 22 and begins his third in v. 23. In this chapter, his ministry in Corinth and Ephesus takes center stage. Priscilla and Aquila make their appearance, so does the powerfully effective speaker Apollos, who received more theology about God and the fulness of the Spirit.
Paul is still on his second missionary journey, along with his team, minus Luke, who will rejoin them in Troas (20:5). The Bereans were nobler than the Thessalonians because the Berans searched the Scriptures. Paul preaches his famous discourse to the Areopagus council.
