Genesis 31:51-53

51Laban also said, ‘I have put this special stone here, and the heap of stones near it. They stand there between your land and my land.

52I will not go past the stones to your side to hurt you. And you must not go past them to my side to hurt me.

53Let the God of Abraham, Nahor, and their ancestors decide if one of us is guilty.’ So Jacob made a promise in the name of the God that his father Isaac worshipped.
