Genesis 23:16–18

Abraham listened to Ephron, and Abraham weighed out for Ephron the silver that he had named in the hearing of the Hittites, four hundred shekels of silver, according to the weights current among the merchants.

So the field of Ephron in Machpelah, which was to the east of Mamre, the field with the cave that was in it and all the trees that were in the field, throughout its whole area, was made over to Abraham as a possession in the presence of the Hittites, before all who went in at the gate of his city.

Abraham agreed with Ephron, and Abraham weighed out to Ephron the silver that he had agreed to in the hearing of the Hethites: four hundred standard shekels of silver. So Ephron’s field at Machpelah near Mamre—the field with its cave and all the trees anywhere within the boundaries of the field—became Abraham’s possession in the sight of all the Hethites who came to the gate of his city.

So Abraham agreed to Ephron’s price and paid the amount he had suggested—400 pieces of silver, weighed according to the market standard. The Hittite elders witnessed the transaction.

So Abraham bought the plot of land belonging to Ephron at Machpelah, near Mamre. This included the field itself, the cave that was in it, and all the surrounding trees. It was transferred to Abraham as his permanent possession in the presence of the Hittite elders at the city gate.

Then Abraham listened to Ephron, and Abraham weighed for Ephron the silver that he had named in the hearing of the Hittites: four hundred shekels of silver at the merchants’ current rate. So the field of Ephron which was in the Machpelah, which was near Mamre—the field and the cave which was in it, with all the trees that were in the field, which were within all its surrounding boundaries—passed to Abraham as a property in the presence of the Hittites, with respect to all who were entering the gate of his city.

And Abraham hearkened unto Ephron; and Abraham weighed to Ephron the silver, which he had named in the audience of the sons of Heth, four hundred shekels of silver, current money with the merchant. And 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 borders round about, were made sure Unto Abraham for a possession in the presence of the children of Heth, before all that went in at the gate of his city.
