Genesis 23:19-20 New King James Version (NKJV)

19. And 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.

20. So the field and the cave that is in it were deeded to Abraham by the sons of Heth as property for a burial place.
