In Genesis 31:51, Laban later points to this same heap and pillar as the agreed-upon boundary witness between them — directly continuing the narrative.

In Genesis 31:52, the pillar erected here is explicitly named as a witness: neither party will cross it to harm the other.

Genesis 28:18-22 shows Jacob's original pillar at Bethel — the same practice of erecting stones to mark covenant moments.

In Exodus 24:4, Moses also sets up pillars of stone in a covenant context, though the pillars there represent the twelve tribes before God rather than a boundary.

In 1 Samuel 7:12, Samuel likewise sets up a single stone as a named memorial marker — similar practice, though that stone commemorates God's help.
