Abraham bought the field and the cave on it from the Hittite people. This became his property, and he used it as a burying place.
Then Abraham left his dead wife and went to talk to the Hittite people. He said,
“I am only a traveler staying in your country. I have no place to bury my wife. Please give me some land so I can bury my wife.”
His sons Isaac and Ishmael buried him in the cave of Machpelah. This cave is in the field of Ephron, the son of Zohar. It was east of Mamre.
