Genesis 31:42, 53

Except the God of my father, the God of Abraham, and the Fear of Isaac, had been with me, surely now hadst thou sent me away empty. God hath seen mine affliction and the labor of my hands, and rebuked thee yesternight.

The God of Abraham, and the God of Nahor, the God of their father, judge betwixt us. And Jacob sware by the Fear of his father Isaac.
