After these things Paul departed from Athens, and came to Corinth.
2He found a certain Jew named Aquila, a man of Pontus by race, who had recently come from Italy, with his wife Priscilla, because Claudius had commanded all the Jews to depart from Rome. He came to them,
3and because he practiced the same trade, he lived with them and worked, for by trade they were tent makers.
4He reasoned in the synagogue every Sabbath, and persuaded Jews and Greeks.
5But when Silas and Timothy came down from Macedonia, Paul was compelled by the Spirit, testifying to the Jews that Jesus was the Christ.
6When they opposed him and blasphemed, he shook out his clothing and said to them, "Your blood be on your own heads! I am clean. From now on, I will go to the Gentiles!"
7He departed there, and went into the house of a certain man named Justus, one who worshiped God, whose house was next door to the synagogue.
8Crispus, the ruler of the synagogue, believed in the Lord with all his house. Many of the Corinthians, when they heard, believed and were baptized.
9The Lord said to Paul in the night by a vision, "Don't be afraid, but speak and don't be silent;
10for I am with you, and no one will attack you to harm you, for I have many people in this city."
11He lived there a year and six months, teaching the word of God among them.
12But when Gallio was proconsul of Achaia, the Jews with one accord rose up against Paul and brought him before the judgment seat,
13saying, "This man persuades men to worship God contrary to the law."
14But when Paul was about to open his mouth, Gallio said to the Jews, "If indeed it were a matter of wrong or of wicked crime, you Jews, it would be reasonable that I should bear with you;
15but if they are questions about words and names and your own law, look to it yourselves. For I don't want to be a judge of these matters."
16He drove them from the judgment seat.
17Then all the Greeks laid hold on Sosthenes, the ruler of the synagogue, and beat him before the judgment seat. Gallio didn't care about any of these things.
18Paul, having stayed after this many more days, took his leave of the brothers, and sailed from there for Syria, together with Priscilla and Aquila. He shaved his head in Cenchreae, for he had a vow.
19He came to Ephesus, and he left them there; but he himself entered into the synagogue, and reasoned with the Jews.
20When they asked him to stay with them a longer time, he declined;
21but taking his leave of them, and saying, "I must by all means keep this coming feast in Jerusalem, but I will return again to you if God wills," he set sail from Ephesus.
22When he had landed at Caesarea, he went up and greeted the assembly, and went down to Antioch.
23Having spent some time there, he departed, and went through the region of Galatia, and Phrygia, in order, establishing all the disciples.
24Now a certain Jew named Apollos, an Alexandrian by race, an eloquent man, came to Ephesus. He was mighty in the Scriptures.
25This man had been instructed in the way of the Lord; and being fervent in spirit, he spoke and taught accurately the things concerning Jesus, although he knew only the baptism of John.
26He began to speak boldly in the synagogue. But when Priscilla and Aquila heard him, they took him aside, and explained to him the way of God more accurately.
27When he had determined to pass over into Achaia, the brothers encouraged him, and wrote to the disciples to receive him. When he had come, he greatly helped those who had believed through grace;
28for he powerfully refuted the Jews, publicly showing by the Scriptures that Jesus was the Christ.

Summary

In Corinth Paul finds Aquila and Priscilla, fellow Jewish tentmakers exiled from Rome by Claudius, and the three work together; when Silas and Timothy arrive Paul gives himself full-time to preaching. Synagogue opposition pushes him next door to the house of Titius Justus, where the synagogue ruler himself believes — and Jesus appears in a vision to assure him there are many of his people in the city. Paul stays eighteen months. When dragged before the proconsul Gallio, the charges are summarily dismissed, securing the gospel a measure of legal protection. Paul finally sails for Syria via Ephesus, dropping off Priscilla and Aquila there, and returning briefly to Antioch before launching his third journey through Galatia and Phrygia. Meanwhile in Ephesus Priscilla and Aquila quietly take aside the gifted but partially informed preacher Apollos and bring him into the fuller gospel, sending him on to Achaia to powerful effect.

Context & background

C. AD 50-52. Corinth (a few miles southwest of modern Korinthos, Greece) was the wealthy, cosmopolitan capital of the Roman province of Achaia, controlling trade across the Isthmus that connects the Peloponnese to mainland Greece. Its reputation for sexual immorality was proverbial ("to act like a Corinthian"). Claudius' expulsion of Jews from Rome (v. 2) is independently confirmed by Suetonius and dated c. AD 49. Tentmaking (Greek *skēnopoios*) likely meant leatherworking, including tents — Paul supported himself with this trade throughout his ministry (1 Corinthians 9:6, 2 Thessalonians 3:8). Gallio (v. 12) is one of Acts' most securely dated figures — an inscription at Delphi fixes his Achaia proconsulship to AD 51-52, anchoring Pauline chronology. Cenchreae (v. 18) was Corinth's eastern port; the vow (likely a temporary Nazirite vow, Numbers 6) ended with shaving the head. Apollos (v. 24) was from Alexandria, Egypt, a major Jewish intellectual center; he becomes a leading figure in 1 Corinthians.

  1. Observe

    Why had Aquila and Priscilla recently come to Corinth when Paul arrived?

  2. Observe

    What did the Lord say to Paul in the vision at Corinth (vv. 9-10), and how long did Paul stay after that?

  3. Interpret

    Apollos was "mighty in the Scriptures," "fervent in spirit," and taught "accurately the things concerning Jesus" — yet he knew "only the baptism of John" (vv. 24-25) and needed Priscilla and Aquila's correction. What does this teach about gifted teachers who have an incomplete understanding?

  4. Interpret

    Jesus told Paul in the vision, "I have many people in this city" (v. 10), referring to Corinthians who had not yet believed. What does this say about how God views those who are not yet Christians?

  5. Apply

    Priscilla and Aquila heard Apollos preaching boldly in the synagogue, recognized his gap, and "took him aside" to explain the way of God more accurately (v. 26). What does their approach model for correcting someone in ministry?

  6. Apply

    Paul worked as a tentmaker alongside his preaching (vv. 2-3), and Jesus' vision did not promise him ease but only presence and protection. How does this challenge or expand your sense of what faithful ministry can look like?
