Genesis 23:13-16

13and he replied to Ephron as everyone listened. “No, listen to me. I will buy it from you. Let me pay the full price for the field so I can bury my dead there.”

14Ephron answered Abraham,

15“My lord, please listen to me. The land is worth 400 pieces of silver, but what is that between friends? Go ahead and bury your dead.”

16So Abraham agreed to Ephron’s price and paid the amount he had suggested—400 pieces of silver, weighed according to the market standard. The Hittite elders witnessed the transaction.
