Genesis 23:9-20

9that he may give me the cave of Machpelah, which is his, which is at the end of his field; for the full money let him give it to me amongst you for a possession of a sepulchre. 10And Ephron was dwelling among the sons of Heth. And Ephron the Hittite answered Abraham, in the ears of the sons of Heth, [even] of all that went in at the gate of his city, saying, 11No, my lord: hear me. The field give I thee; and the cave that is in it, to thee I give it; before the eyes of the sons of my people give I it thee: bury thy dead. 12And Abraham bowed down before the people of the land; 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. 17So the field of Ephron, which was at Machpelah, which was before Mamre, the field, and the cave that was in it, and all the trees that were in the field, that were in all its borders round about, 18were assured to Abraham for a possession before the eyes of the sons of Heth, before all who went in at the gate of his city. 19And after this, Abraham buried Sarah his wife in the cave of the field at Machpelah, opposite to Mamre: that is Hebron, in the land of Canaan. 20And the field and the cave that was in it were assured to Abraham for a possession of a sepulchre by the sons of Heth.
