To whom were the promises that began with Abraham repeated in Paul's Acts 13 rehearsal?
The promises originally given to Abraham were repeated to Isaac and then to Jacob. The twelve sons of Jacob carried that same promise onward through their sojourn. This line is traced from Genesis 12, before the prophets later spoke of Christ's first coming.
Les explains that Paul, while at Antioch of Pisidia, rehearses the history of the Jewish nation as Stephen did in chapter 7, beginning with Abraham, Isaac, and Jacob. In that Acts 13 review, the promises that started with Abraham are repeated to Isaac and then to Jacob, and the twelve sons of Jacob carry them on through their sojourn. Les also notes that the prophets—Isaiah, Jeremiah, and Ezekiel—all spoke of Christ's first coming. This chapter, he says, contains a basic doctrine about the only begotten Son of God, but the promise line itself runs from Abraham through Isaac, Jacob, and the twelve sons.
