Genesis 23:14

12Abraham bowed himself down before the people of the land.

13He spoke to Ephron in the audience of the people of the land, saying, “But if you will, please hear me. I will give the price of the field. Take it from me, and I will bury my dead there.”

14Ephron answered Abraham, saying to him,

15“My lord, listen to me. What is a piece of land worth four hundred shekels of silver between me and you? Therefore bury your dead.”

16Abraham listened to Ephron. Abraham weighed to Ephron the silver which he had named in the hearing of the children of Heth, four hundred shekels of silver, according to the current merchants’ standard.
