Genesis 23:13-16

13and he spoke to Ephron, in the ears of the people of the land, saying, But if only thou wouldst listen to me, I give the money for the field: take [it] of me, and I will bury my dead there.

14And Ephron answered Abraham, saying to him,

15My lord, hearken to me. A field of four hundred shekels of silver, what is that between me and thee? bury therefore thy dead.

16And Abraham hearkened to Ephron; and Abraham weighed to Ephron the money that he had named in the ears of the sons of Heth — four hundred shekels of silver, current with the merchant.
