Genesis 31:49-53

49— and Mizpah; for he said, Let Jehovah watch between me and thee, when we shall be hidden one from another:

50if thou shouldest afflict my daughters, or if thou shouldest take wives besides my daughters, — no man is with us; see, 1God is witness between me and thee!

51And Laban said to Jacob, Behold this heap, and behold the pillar which I have set up between me and thee:

52[let] this heap be witness, and the pillar a witness, that neither I pass this heap [to go] to thee, nor thou pass this heap and this pillar [to come] to me, for harm.

53The 2God of Abraham, and the 3God of Nahor, the 4God of their father, judge between us! And Jacob swore by the fear of his father Isaac.
