Acts 18:26

And he began to speak boldly in the synagogue For the Jews were not all ready to listen to announcements of the approach of the Messiah. The speaker must be prepared with arguments as well as courage who dwelt on this theme, about which the Jews had been deluded by many impostors.

But when Priscilla and Aquila heard him] This is the commencement of a new sentence in the original, and the oldest texts put the name of the wife before that of her husband as in Acts 18:18. By joining her in this marked way with Aquila in the communications with Apollos, the historian indicates that she was a woman of great power and zeal among the Christians. It has been suggested that she was perhaps a born Jewess and her husband not so, which might account for the prominence given in several places to her name. It may be noted here, as so often, that Aquila and his wife, like the other Judæo-Christians, still attended the worship of the synagogue.

they took him unto them He would be much more in sympathy with them than with the Jewish congregation. He was prepared to accept the Messiah, but did not yet understand that Jesus was He.

and expounded unto him the way of God more carefully] The adverb here is the same as in the previous verse, and the use of it seems to shew that the studies of Aquila and his wife in the Scriptures had been of the same earnest kind as those of Apollos. By the "way of God" we must understand God's further working out of the Old Testament prediction in the closing events of the life of Jesus, and in the gift of the Holy Ghost. That Joel's prophecy, quoted by St Peter on the day of Pentecost (Acts 2:16), had been thus fulfilled, was new learning for the eloquent Alexandrian. As also the newly appointed means of grace in baptism and the breaking of bread, with the promise of salvation to faith in Christ. These also may be included as part of the "way of God," being means whereby men are brought nearer to Him.
