Genesis 31:44-45

The tall stone and the heap were signs of the agreement that Jacob and Laban had made. If either of them passed that place (see verse 52), they would see the signs. The signs would remind them about the agreement. Also, when they were far from that place, they would remember the signs. They would remember that they had made the signs. And they would remember the *offering and the meal. (See verse 54.) That too would remind them of the agreement.

v47 Laban called that place Jegar-sahadutha, but Jacob called it Galeed. v48 Laban said, ‘This heap is now a sign of the agreement between you and me.’ That is the reason why they called it Galeed. v49 Laban called the tall stone Mizpah. He said, ‘Let the *Lord be a guard between you and me, when we are absent from each other. v50 If you do evil things to my daughters, God will see. If you take other wives in addition to my daughters, God will see. Although nobody is with us, God is a witness between you and me.’
