The purchase of the field and of the cave that is therein was from the children of Heth.
So Ephron's field at Machpelah near Mamre-- the field with its cave and all the trees anywhere within the boundaries of the field-- became
Abraham's possession in the presence of all the Hittites who came to the gate of his city.
After this, Abraham buried his wife Sarah in the cave of the field at Machpelah near Mamre (that is, Hebron) in the land of Canaan.
The field with its cave passed from the Hittites to Abraham as a burial place.
