Genesis 23:17-20

17So Abraham secured Ephron’s field in Machpelah, next to Mamre, including the field, the cave that was in it, and all the trees that were in the field and all around its border,

18as his property in the presence of the sons of Heth before all who entered the gate of Ephron’s city.

19After this Abraham buried his wife Sarah in the cave in the field of Machpelah next to Mamre (that is, Hebron) in the land of Canaan.

20So Abraham secured the field and the cave that was in it as a burial site from the sons of Heth.
