Genesis 31:51-53

Young's Literal Translation

⁵¹ And Laban saith to Jacob, `Lo, this heap, and lo, the standing pillar which I have cast between me and thee;

⁵² this heap [is] witness, and the standing pillar [is] witness, that I do not pass over this heap unto thee, and that thou dost not pass over this heap and this standing pillar unto me -- for evil;

⁵³ the God of Abraham and the God of Nahor, doth judge between us -- the God of their father,' and Jacob sweareth by the Fear of his father Isaac.
