Genesis 23:15-19

“My lord, listen to me: a plot of land worth four hundred shekels of silver—what is that between me and you? So bury your dead.”

Abraham listened to Ephron; and Abraham weighed out for Ephron the silver which he had named in the presence of the sons of Heth, four hundred shekels of silver, currency acceptable to a merchant.

So Ephron’s field, which was in Machpelah, which faced Mamre, the field and the cave which was in it, and all the trees which were in the field, that were within all the confines of its border, were deeded over

to Abraham as a possession in the presence of the sons of Heth, before all who entered the gate of his city.

After this, Abraham buried his wife Sarah in the cave of the field of Machpelah facing Mamre (that is, Hebron), in the land of Canaan.
