Genesis 31:50-53 Holman Christian Standard Bible (HCSB)
50 If you mistreat my daughters or take other wives, though no one is with us, understand that God will be a witness between you and me.” 51 Laban also said to Jacob, “Look at this mound and the marker I have set up between you and me. 52 This mound is a witness and the marker is a witness that I will not pass beyond this mound to you, and you will not pass beyond this mound and this marker to do me harm. 53 The God of Abraham, and the gods of Nahor—the gods of their father[a]—will judge between us.” And Jacob swore by the Fear of his father Isaac.
