Thematic Bible: Selling land

Then Ephron answered Abraham, saying to him, "My lord, listen to me; a piece of land worth four hundred shekels of silver, what is that between me and you? So bury your dead." Abraham listened to Ephron; and Abraham weighed out for Ephron the silver which he had named in the hearing of the sons of Heth, four hundred shekels of silver, commercial standard.
