Genesis 31:48-52

And Laban said, This heap is a witness between me and thee this day. Therefore was the name of it called Galeed;

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

If 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.

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

This 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.
