Genesis 31:49-53

49and Mizpah (watchtower), for Laban said, “May the Lord watch between you and me when we are absent from one another.

50If you should mistreat (humiliate, oppress) my daughters, or if you should take other wives besides my daughters, although no one is with us [as a witness], see and remember, God is witness between you and me.”

51Laban said to Jacob, “Look at this mound [of stones] and look at this pillar which I have set up between you and me.

52This mound is a witness, and this pillar is a witness, that I will not pass by this mound to harm you, and that you will not pass by this mound and this pillar to harm me.

53The God of Abraham [your father] and the God of Nahor [my father], and the god [the image of worship] of their father [Terah, an idolater], judge between us.” But Jacob swore [only] by [the one true God] the Fear of his father Isaac.
