Matthew 21:28

A certain man had two sons, &c. The ancient interpreters, by the first son generally understand the Gentiles, as also publicans and scandalous sinners; and by the second, the Jewish people. The Gentiles, &c. who at the first did not, would not worship and serve God; yet afterwards they, as also publicans, and many sinners, received the faith, and being converted, became faithful servants of God, and saints: the Jews, or the greatest part of them, who pretended to be God's servants, and his people, rejected the gospel and their Messias; therefore this commination follows, the publicans, &c. shall go before you into the kingdom of God. (Witham) --- By these two sons are to be understood, says St. John Chrysostom, the Gentiles and the Jewish people; the latter our Redeemer wishes to make sensible of their own great ingratitude, and of the ready obedience of the cast-off Gentiles. For they having never heard the law, nor promised obedience have still shewn their submission by their works; whereas the Jews after promising to obey the voice of God, had neglected the performance. (Hom. lxviii.)
