Genesis 31:43-50

Laban replied to Jacob, “These women are my daughters, these children are my grandchildren; and the flocks are mine. In fact, everything you see belongs to me. But from today I will not be able to do anything more for my daughters and grandchildren. Come now, let’s form a covenant between you and me. Let it endure as a witness between us.” So Jacob took a stone, set it up as a pillar, and in the presence of his relatives, he said to them, “Everyone gather stones, and place them here in a pile.” And they did so, and afterward, they ate together next to the heap of stones. Laban and Jacob named the place in both languages, Aramaic and Hebrew, calling it Witness Heap. And Laban said, “Today, this heap of stones will be a witness between you and me of our enduring friendship.” He called it Witness Heap and Watchpost, for Laban declared, “May YAHWEH keep his eyes on us when we are absent from each other. If you mistreat my daughters or marry other women besides my daughters, remember that even though no one else is with us, God is watching us.
