This "grove" must have been within sight of or "facing" Machpelah (q.v.). The site of Mamre has been identified with Ballatet Selta, i.e., "the oak of rest", where there is a tree called "Abraham's oak," about a mile and a half west of Hebron. Others identify it with er-Rameh, 2 miles north of Hebron.
