Genesis 31:51-53

New Living Translation

⁵¹ “See this pile of stones,” Laban continued, “and see this monument I have set between us. ⁵² They stand between us as witnesses of our vows. I will never pass this pile of stones to harm you, and you must never pass these stones or this monument to harm me. ⁵³ I call on the God of our ancestors—the God of your grandfather Abraham and the God of my grandfather Nahor—to serve as a judge between us.”

So Jacob took an oath before the fearsome God of his father, Isaac,^[a] to respect the boundary line.
