Genesis 23:18

unto Abraham for a possession in the presence of the children of Heth, before all that went in at the gate of his city. The language is that of a formal instrument used in the transfer of real estate; the location of the field is given: before Mamre, over against the grove of Mamre, adjoining the cave Machpelah, which was at one end of it; the description of the property is accurate and includes even the trees on the plot itself and on its borders on every side. The field was thus conveyed to Abraham with all the appurtenances thereof, the record of the transaction being very minute and the witnesses expressly mentioned.
