17 Then all of them seized Sosthenes, the official of the synagogue, and beat him in front of the tribunal. But Gallio paid no attention to any of these things.
18 After staying there for a considerable time, Paul said farewell to the believers and sailed for Syria, accompanied by Priscilla and Aquila. At Cenchreae he had his hair cut, for he was under a vow. 19 When they reached Ephesus, he left them there, but first he himself went into the synagogue and had a discussion with the Jews. 20 When they asked him to stay longer, he declined; 21 but on taking leave of them, he said, "I will return to you, if God wills." Then he set sail from Ephesus.
22 When he had landed at Caesarea, he went up to Jerusalem and greeted the church, and then went down to Antioch. 23 After spending some time there he departed and went from place to place through the region of Galatia and Phrygia, strengthening all the disciples.
24 Now there came to Ephesus a Jew named Apollos, a native of Alexandria. He was an eloquent man, well-versed in the scriptures. 25 He had been instructed in the Way of the Lord; and he spoke with burning enthusiasm and taught accurately the things concerning Jesus, though he knew only the baptism of John. 26 He began to speak boldly in the synagogue; but when Priscilla and Aquila heard him, they took him aside and explained the Way of God to him more accurately. 27 And when he wished to cross over to Achaia, the believers encouraged him and wrote to the disciples to welcome him. On his arrival he greatly helped those who through grace had become believers, 28 for he powerfully refuted the Jews in public, showing by the scriptures that the Messiah is Jesus.

(Read Acts 18:12-17)
Paul was about to show that he did not teach men to worship God contrary to law; but the judge would not allow the Jews to complain to him of what was not within his office. It was right in Gallio that he left the Jews to themselves in matters relating to their religion, but yet would not let them, under pretence of that, persecute another. But it was wrong to speak slightly of a law and religion which he might have known to be of God, and which he ought to have acquainted himself with. In what way God is to be worshipped, whether Jesus be the Messiah, and whether the gospel be a Divine revelation, are not questions of words and names, they are questions of vast importance. Gallio spoke as if he boasted of his ignorance of the Scriptures, as if the law of God was beneath his notice. Gallio cared for none of these things. If he cared not for the affronts of bad men, it was commendable; but if he concerned not himself for the abuses done to good men, his indifference was carried too far. And those who see and hear of the sufferings of God's people, and have no feeling with them, or care for them, who do not pity and pray for them, are of the same spirit as Gallio, who cared for none of these things.

(Read Acts 18:18-23)
While Paul found he laboured not in vain, he continued labouring. Our times are in God's hand; we purpose, but he disposes; therefore we must make all promises with submission to the will of God; not only if providence permits, but if God does not otherwise direct our motions. A very good refreshment it is to a faithful minister, to have for awhile the society of his brethren. Disciples are compassed about with infirmity; ministers must do what they can to strengthen them, by directing them to Christ, who is their Strength. Let us earnestly seek, in our several places, to promote the cause of Christ, forming plans that appear to us most proper, but relying on the Lord to bring them to pass if he sees good.
Commentary on Acts 18:24-28
(Read Acts 18:24-28)
Apollos taught in the gospel of Christ, as far as John's ministry would carry him, and no further. We cannot but think he had heard of Christ's death and resurrection, but he was not informed as to the mystery of them. Though he had not the miraculous gifts of the Spirit, as the apostles, he made use of the gifts he had. The dispensation of the Spirit, whatever the measure of it may be, is given to every man to profit withal. He was a lively, affectionate preacher; fervent in spirit. He was full of zeal for the glory of God and the salvation of precious souls. Here was a complete man of God, thoroughly furnished for his work. Aquila and Priscilla encouraged his ministry, by attendance upon it. They did not despise Apollos themselves, or undervalue him to others; but considered the disadvantages he had laboured under. And having themselves got knowledge in the truths of the gospel by their long intercourse with Paul, they told what they knew to him. Young scholars may gain a great deal by converse with old Christians. Those who do believe through grace, yet still need help. As long as they are in this world, there are remainders of unbelief, and something lacking in their faith to be perfected, and the work of faith to be fulfilled. If the Jews were convinced that Jesus is Christ, even their own law would teach them to hear him. The business of ministers is to preach Christ. Not only to preach the truth, but to prove and defend it, with meekness, yet with power.
