Bede : All the men were about twelve, etc. But the judgments of God are a great abyss. Behold, recently deemed unworthy of the visitation of the apostles, Asia is now consecrated by the Apostolic number and elevated by the prophetic gift. And it should be noted that the Holy Spirit also here showed the signs of his coming upon the twelve disciples, and above upon the one hundred and twenty, which is the number twelve multiplied by ten, that sign in Jerusalem, this in Ephesus, which is a city of the Greeks. I believe to show that whether a person believes from among the Jews or the Gentiles, they only who communicate with the unity of the Catholic and Apostolic Church are fulfilled. — Commentary on Acts
