Genesis 23:16-18

Revised Standard Version

¹⁶ Abraham agreed with Ephron; and Abraham weighed out for Ephron the silver which he had named in the hearing of the Hittites, four hundred shekels of silver, according to the weights current among the merchants.

¹⁷ So the field of Ephron in Mach-pe′lah, which was to the east of Mamre, the field with the cave which was in it and all the trees that were in the field, throughout its whole area, was made over ¹⁸ to Abraham as a possession in the presence of the Hittites, before all who went in at the gate of his city.
