Genesis 31:23 describes Laban catching up in Gilead, leading to the covenant and heap of stones here.

Genesis 31:44 initiates the covenant, which the heap in 31:48 witnesses.

Genesis 31:52 reaffirms the heap as a witness against harm, expanding the covenant terms.

Joshua 24:27 uses a stone as a witness against Israel, similar to the heap witnessing Jacob and Laban's covenant.

In Joshua 22:27, the eastern tribes build an altar 'that it may be a witness between us' — directly paralleling Laban's heap as covenant testimony between parties.
