Dissembling deceitfully, Ephron then offered to give Abraham the field without compensation, but when Abraham insisted upon paying for it, Ephron said: "My lord, hearken unto me. A piece of land worth four hundred shekels of silver, what is that betwixt me and thee?" showing only too well that the money was of the greatest consequence to him. Abraham understood his words, and when he came to pay for the field, he weighed out the sum agreed upon between them in the best of current coin. A deed, signed by four witnesses, was drawn up, and the field of Ephron, which was in Machpelah, the field, and the cave which was therein, were made sure unto Abraham and his descendants for all times.
