Genesis 23:11-20

“No, my lord, hear me: I give you the field and the cave that is in it; I give it to you in the presence of the sons of my people. I give it to you. Bury your dead!” Then Abraham bowed himself down before the people of the land; and he spoke to Ephron in the hearing of the people of the land, saying, “If you will give it, please hear me. I will give you money for the field; take it from me and I will bury my dead there.” And Ephron answered Abraham, saying to him, “My lord, listen to me; the land is worth four hundred shekels of silver. What is that between you and me? So bury your dead.” And Abraham listened to Ephron; and Abraham weighed out the silver for Ephron which he had named in the hearing of the sons of Heth, four hundred shekels of silver, currency of the merchants. So the field of Ephron which was in Machpelah, which was before Mamre, the field and the cave which was in it, and all the trees that were in the field, which were within all the surrounding borders, were deeded to Abraham as a possession in the presence of the sons of Heth, before all who went in at the gate of his city. And after this, Abraham buried Sarah his wife in the cave of the field of Machpelah, before Mamre (that is, Hebron) in the land of Canaan. So the field and the cave that is in it were deeded to Abraham by the sons of Heth as property for a burial place.
