Acts 18 [18.] Paul, having stayed after this many more days, took his leave of the brothers, [a] and sailed from there for Syria, together with Priscilla and Aquila. He shaved his head in Cenchreae, for he had a vow. He came to Ephesus, and he left them there; but he himself entered into the synagogue, and reasoned with the Jews. When they asked him to stay with them a longer time, he declined; but 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.
Acts 18 [22.] When he had landed at Caesarea, he went up and greeted the assembly, and went down to Antioch. Having spent some time there, he departed, and went through the region of Galatia, and Phrygia, in order, establishing all the disciples. Now a certain Jew named Apollos, an Alexandrian by race, an eloquent man, came to Ephesus. He was mighty in the Scriptures. This 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. He 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.
Acts 18 [27.] When 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; for he powerfully refuted the Jews, publicly showing by the Scriptures that Jesus was the Christ.
a. Acts 18:18 The word for “brothers” here and where the context allows may also be correctly translated “brothers and sisters” or “siblings.”
