Genesis 31:52-54 New International Version - UK (NIVUK)
52 This heap is a witness, and this pillar is a witness, that I will not go past this heap to your side to harm you and that you will not go past this heap and pillar to my side to harm me. 53 May the God of Abraham and the God of Nahor, the God of their father, judge between us.’
So Jacob took an oath in the name of the Fear of his father Isaac. 54 He offered a sacrifice there in the hill country and invited his relatives to a meal. After they had eaten, they spent the night there.
