Genesis 31:43

Laban answered... — Laban does not attempt any reply to Jacob’s angry invectives, but answers affectionately. Why should he wish to injure Jacob, and send him away empty? All that he had was still Laban’s in the best of senses; for were not Rachel and Leah his daughters? And were not their children his grandsons? How was it possible that he could wish to rob them? He proposes, therefore, that they should make a covenant, by which Jacob should bind himself to deal kindly with his daughters, and to take no other wife; while he promises for himself that he would do Jacob no wrong. Jacob therefore sets up a large stone, as a pillar and memorial; and Laban subsequently does the same; while, probably between the two hills on which they had severally encamped (Genesis 31:25), they collect a large mass of other stones, on which they feast together, in token of friendship (Genesis 26:30).
