Genesis 31:45-52
45Jacob took a stone and set it upright as a pillar.
46Jacob called his family around, "Get stones!" They gathered stones and heaped them up and then ate there beside the pile of stones.
47Laban named it in Aramaic, Yegar-sahadutha (Witness Monument); Jacob echoed the naming in Hebrew, Galeed (Witness Monument).
48Laban said, "This monument of stones will be a witness, beginning now, between you and me." (That''s why it is called Galeed--Witness Monument.)
49It is also called Mizpah (Watchtower) because Laban said, "GOD keep watch between you and me when we are out of each other''s sight.
50If you mistreat my daughters or take other wives when there''s no one around to see you, God will see you and stand witness between us."
51Laban continued to Jacob, "This monument of stones and this stone pillar that I have set up is a witness,
52a witness that I won''t cross this line to hurt you and you won''t cross this line to hurt me.
