Genesis 23:16-20 New King James Version (NKJV)
16 And Abraham listened to Ephron; and Abraham weighed out the silver for Ephron which he had named in the hearing of the sons of Heth, four hundred shekels of silver, currency of the merchants.
17 So the field of Ephron which was in Machpelah, which was before Mamre, the field and the cave which was in it, and all the trees that were in the field, which were within all the surrounding borders, were deeded 18 to Abraham as a possession in the presence of the sons of Heth, before all who went in at the gate of his city.
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.
Genesis 23:16-20 New International Version (NIV)
16 Abraham agreed to Ephron’s terms and weighed out for him the price he had named in the hearing of the Hittites: four hundred shekels of silver, according to the weight current among the merchants.
17 So Ephron’s field in Machpelah near Mamre—both the field and the cave in it, and all the trees within the borders of the field—was deeded 18 to Abraham as his property in the presence of all the Hittites who had come to the gate of the city. 19 Afterward Abraham buried his wife Sarah in the cave in the field of Machpelah near Mamre (which is at Hebron) in the land of Canaan. 20 So the field and the cave in it were deeded to Abraham by the Hittites as a burial site.
