Genesis 31:52-54 World English Bible (WEB)
52 May this heap be a witness, and the pillar be a witness, that I will not pass over this heap to you, and that you will not pass over this heap and this pillar to me, for harm. 53 The God of Abraham, and the God of Nahor, the God of their father, judge between us.” Then Jacob swore by the fear of his father, Isaac. 54 Jacob offered a sacrifice in the mountain, and called his relatives to eat bread. They ate bread, and stayed all night in the mountain.
