Genesis

¹⁵My lord, hearken unto me: a piece of land worth four hundred shekels of silver, what is that betwixt me and thee? bury therefore thy dead. ¹⁶And Abraham hearkened unto Ephron; and Abraham weighed to Ephron the silver, which he had named in the audience of the children of Heth, four hundred shekels of silver, current money with the merchant. ¹⁷So the field of Ephron, which was in Machpelah, which was before Mamre, the field, and the cave which was therein, and all the trees that were in the field, that were in all the border thereof round about, were made sure ¹⁸unto Abraham for a possession in the presence of the children of Heth, before all that went in at the gate of his city. ¹⁹And after this, Abraham buried Sarah his wife in the cave of the field of Machpelah before Mamre (the same is Hebron), in the land of Canaan. ²⁰And the field, and the cave that is therein, were made sure unto Abraham for a possession of a buryingplace by the children of Heth.
