Genesis 23:10-16

23:10 (Now Ephron was sitting among the sons of Heth.) Ephron the Hethite replied to Abraham in the hearing of the sons of Heth – before all who entered the gate of his city – 23:11 “No, my lord! Hear me out. I sell you both the field and the cave that is in it. In the presence of my people I sell it to you. Bury your dead.”

23:12 Abraham bowed before the local people 23:13 and said to Ephron in their hearing, “Hear me, if you will. I pay to you the price of the field. Take it from me so that I may bury my dead there.”

23:14 Ephron answered Abraham, saying to him, 23:15 “Hear me, my lord. The land is worth 400 pieces of silver, but what is that between me and you? So bury your dead.”

23:16 So Abraham agreed to Ephron’s price and weighed out for him the price that Ephron had quoted in the hearing of the sons of Heth – 400 pieces of silver, according to the standard measurement at the time.
