Genesis 23:16 records Abraham weighing silver to Ephron for the purchase. This verse references that same transaction as the legal basis for the burial site.

Genesis 49:31 lists the patriarchs buried in that same purchased field. Machpelah became the family tomb across generations.

Genesis 23:3 records Abraham approaching the Hittites to buy burial land. This verse completes that story: the field he purchased is where he rests.

Genesis 23:19 is the burial site Abraham purchased for Sarah — the same cave of Machpelah where Abraham himself is now laid to rest.
