Genesis 31:51-53

51Laban also said to Jacob, “Look at this mound and the marker I have set up between you and me.

52This mound is a witness and the marker is a witness that I will not pass beyond this mound to you, and you will not pass beyond this mound and this marker to do me harm.

53The God of Abraham, and the gods of Nahor — the gods of their father  — will judge between us.” And Jacob swore by the Fear of his father Isaac.
