Young's Literal Translation

¹⁸ to Abraham by purchase, before the eyes of the sons of Heth, among all entering the gate of his city.

¹⁹ And after this hath Abraham buried Sarah his wife at the cave of the field of Machpelah before Mamre (which [is] Hebron), in the land of Canaan;

²⁰ and established are the field, and the cave which [is] in it, to Abraham for a possession of a burying-place, from the sons of Heth.
