'God of Our Fathers' in the Bible

The God of Abraham and of Isaac and of Jacob, the God of our fathers, has glorified His son Jesus, whom you delivered up, denying Him in the presence of Pilate, when he had decided to let Him go.

The God of our fathers raised up Jesus, whom you killed and hanged on a tree.

And he said, The God of our fathers has chosen you to know His will and to see the Just One, and to hear a voice out of His mouth.
