Genesis 23:13-16

13and he spoke to Ephron in the hearing of the people of the land, saying, “If you will give it, please hear me. I will give you money for the field; take it from me and I will bury my dead there.”

14And Ephron answered Abraham, saying to him,

15“My lord, listen to me; the land is worth four hundred shekels of silver. What is that between you and me? So bury your dead.”

16And 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.
