Genesis 31:47

Now come, let’s make a covenant, you and I. Let it be for a witness between me and you.”

Jacob took a stone, and set it up for a pillar.

Jacob said to his relatives, “Gather stones.” They took stones, and made a heap. They ate there by the heap.

Laban said, “This heap is witness between me and you today.” Therefore it was named Galeed

and Mizpah, for he said, “The LORD watch between me and you, when we are absent one from another.

If you afflict my daughters, or if you take wives in addition to my daughters, no man is with us; behold, God is witness between me and you.”
