Genesis 23:17; Genesis 23:18

17 So Ephron's field, which was in Machpelah, which faced Mamre, the field and cave which was in it, and all the trees which were in the field, that were within all the confines of its border, were deeded over

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