Charles Ellicott Commentary Acts 3:25

"Ye are the sons of the prophets, and of the covenant which God made with your fathers, saying unto Abraham, And in thy seed shall all the families of the earth be blessed." — Acts 3:25 (ASV)

And of the covenant... — It is a significant indication of the unity of apostolic teaching, which St. Luke aimed to bring before his readers, that St. Peter thus refers chiefly to the covenant made with Abraham (Genesis 12:3), with as full an emphasis as St. Paul does when he had learned to see that it implicitly involved the calling of the Gentiles into the kingdom of Christ (Galatians 3:8).
