Charles Ellicott Commentary Acts 7:8

"And he gave him the covenant of circumcision: and so [Abraham] begat Isaac, and circumcised him the eighth day; and Isaac [begat] Jacob, and Jacob the twelve patriarchs." — Acts 7:8 (ASV)

And he gave him the covenant . . .—Here we trace an indirect reference to the charge that he had spoken “against the customs.” He does not deny the specific charge that he had said that Jesus of Nazareth would change them. He probably had taught that the change was about to come.

He does assert:

1. That the covenant of circumcision followed the promise to Abraham, and therefore was not the ground of his election, and so lays the foundation for St. Paul’s argument in Galatians 3:17.
2. That, though part of a provisional, not of a permanent, system, it came from God’s appointment, and therefore was to be spoken of with all reverence, and so he clears himself from the charge of blasphemy.

The twelve patriarchs.—On the meaning of the word see Note on Acts 2:29. Here it is applied to the sons of Jacob, as being, each of them, the founder of a patria, or family.
