Genesis 31:49-53

31:49 It was also called Mizpah because he said, “May the Lord watch between us when we are out of sight of one another. 31:50 If you mistreat my daughters or if you take wives besides my daughters, although no one else is with us, realize that God is witness to your actions.”

31:51 “Here is this pile of stones and this pillar I have set up between me and you,” Laban said to Jacob. 31:52 “This pile of stones and the pillar are reminders that I will not pass beyond this pile to come to harm you and that you will not pass beyond this pile and this pillar to come to harm me. 31:53 May the God of Abraham and the god of Nahor, the gods of their father, judge between us.” Jacob took an oath by the God whom his father Isaac feared.
