Genesis 23:14

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

And he spake unto Ephron in the audience of the people of the land, saying, But if thou [wilt give it], I pray thee, hear me: I will give thee money for the field; take [it] of me, and I will bury my dead there.

My lord, hearken unto me: the land [is worth] four hundred shekels of silver; what [is] that betwixt me and thee? bury therefore thy dead.

And Abraham hearkened unto Ephron; and Abraham weighed to Ephron the silver, which he had named in the audience of the sons of Heth, four hundred shekels of silver, current [money] with the merchant.
