‘ “The God of Abraham and the god of Nahor, the gods of their father, judge between us.” And Jacob swore by the Fear of his father Isaac.'
Each now swears by the God he worships. Jacob swear by Yahweh, the God of Abraham, in the title ‘the Fear' (‘the Awesome One') given by his father Isaac, and Laban swears by the god of Nahor. Each swears by the God of his father.
