‏ Genesis 23:16-18

16Abraham listened to Ephron, and Abraham aweighed out for Ephron the silver that he had named in the hearing of the Hittites, four hundred shekels of silver, according to the weights current among the merchants.

17So bthe field of Ephron in Machpelah, which was to the east of Mamre, the field with the cave that was in it and all the trees that were in the field, throughout its whole area, was made over 18to Abraham as a possession in the presence of the Hittites, before all who went in at the gate of his city.
