Chapter 18
[Acts 18:2] -- Because Claudius had commanded all Jews to depart from Rome. Josephus narrates that this happened in the ninth year of Claudius. Suetonius the historian reports it in this way: Claudius expelled the Jews from Rome, as they were continually making disturbances at the instigation of Chrestus. Whether he meant to restrain and suppress the Jews making disturbances against Christ, or also wished to expel the Christians as related religious members, it is not at all clear.
[Acts 18:3] -- They were of the tent-making trade. As exiles in the land and strangers, they build tents for themselves to use on the way; σκῆναι in Greek are called tabernacles, deriving the etymology from shading, among which shade is called σκία; σκῆναι or σκηνώματα mean something like little shades, which the ancients formed from woolen, wooden, or Cilician cloths, or from the leaves or branches of trees. Mystically, just as Peter by fishing draws us from the waves of the world through the nets of faith, so Paul by setting up the tents of protection defends us from the rain of sins, the heat of temptations, and the winds of treacheries, both by word and by deed. At this point, there are two verses in Greek that are not found in some of our manuscripts. He discussed in the synagogue every Sabbath and persuaded Jews and Greeks. Then follows what both manuscripts have, added:
[Acts 18:18] -- When Silas and Timothy came from Macedonia, and so forth. Who had his hair cut in Cenchreae for he had a vow. Cenchreae is a port of Corinth, where he cut his hair due to a vow because, according to the law of Moses, those who vowed themselves to God were commanded to let their hair grow as long as they wished to be Nazirites, and afterward to cut it and offer it to the fire. Therefore, Paul did this, not indeed forgetting what he had decided with the other apostles in Jerusalem about the abolition of the law, but lest those who had believed from among the Jews be scandalized, he pretended to be a Jew in order to win the Jews. Some manuscripts have in the plural number "They shaved their head, and had a vow," meaning Priscilla and Aquila. But the distinguished doctors of the Church Jerome and Augustine, each in their letters, put it in the singular number and interpret it concerning Paul. Jerome writes thus: "Bidding farewell to the brothers, he sailed to Syria, and with him Priscilla and Aquila, and he had his head shaved in Cenchreae for he had a vow."
[Acts 18:21-22] -- He departed from Ephesus, and descending, he went up to Caesarea and greeted the church. He says Caesarea, the metropolis of Cappadocia. For he had not yet come to Syria of Phoenicia. Formerly called Mosacha from Mosoc, the son of Japheth, later it received the name Caesarea from Caesar Augustus.
[Acts 18:27] -- When he came, he conferred much with those who believed. For he vigorously confuted the Jews. Another translation has: He greatly benefited the believers by grace. This is what the Apostle writes to the Achaians: "I planted, Apollos watered" (I Cor. III).
