Genesis 23:17-19

17So the field of Ephron which was in Machpelah, which was before Mamre, the field and the cave which was in it, and all the trees that were in the field, which were within all the surrounding borders, were deeded

18to Abraham as a possession in the presence of the sons of Heth, before all who went in at the gate of his city.

19And after this, Abraham buried Sarah his wife in the cave of the field of Machpelah, before Mamre (that is, Hebron) in the land of Canaan.
