Genesis 31:51 KJV

49And Mizpah; for he said, The LORD watch between me and thee, when we are absent one from another.

50If thou shalt afflict my daughters, or if thou shalt take other wives beside my daughters, no man is with us; see, God is witness betwixt me and thee.

51And Laban said to Jacob, Behold this heap, and behold this pillar, which I have cast betwixt me and thee:

52This heap be witness, and this pillar be witness, that I will not pass over this heap to thee, and that thou shalt not pass over this heap and this pillar unto me, for harm.

53The God of Abraham, and the God of Nahor, the God of their father, judge betwixt us. And Jacob sware by the fear of his father Isaac.
