John Chrysostom, on Acts 13:16

Behold Barnabas giving place to Paul - how should it be otherwise? - to him whom he brought from Tarsus; just as we find John on all occasions giving way to Peter: and yet Barnabas was more looked up to than Paul: true, but they had an eye only to the common advantage. "Then Paul stood up," it says - this was a custom of the Jews - "and beckoned with his hand." And see how he prepares the way beforehand for his discourse: having first praised them, and showed his great regard for them in the words, "ye that fear God," he so begins his discourse. And he says not, Ye proselytes, since it was a term of disadvantage. "The God of this people chose our fathers: and the people" - See, he calls God Himself their God peculiarly, Who is the common God of men; and shows how great from the first were His benefits, just as Stephen does. This they do to teach them, that now also God has acted after the same custom, in sending His own Son; as Christ Himself does in the parable of the vineyard - "And the people," he says, "He exalted when it sojourned in the land of Egypt" - and yet the contrary was the case: true, but they increased in numbers; moreover, the miracles were wrought on their account: "and with an high arm brought He them out of it." Of these things (the wonders) which were done in Egypt, the prophets are continually making mention.
