Genesis 23:16-18

New International Version - UK

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 legally made over ¹⁸ to Abraham as his property in the presence of all the Hittites who had come to the gate of the city.
