MAM'RE, a place near Hebron, so called after the Amorite chief, Gen 14:13, Jud 6:24; Gen 23:19; Gen 35:27, and it is also the name of a plain and a grove at Hebron by which Abraham dwelt and entertained three angels. Gen 13:18; Gen 18:1. It was near Machpelah. Gen 23:17, Acts 1:19; Gen 25:9; Gen 49:30; Gen 50:13. The grove of terebinths is supposed to have been the place called by the Arabs er-Rameh or Ramet-et-Khulil , one hour from Hebron.
The site of Mamre is shown, on the sheet-maps of the Palestine Exploration Fund, at Ballatet Selta, or "oak of rest," a fine old tree near the modern Russian hospice. The tree is called Abraham's Oak. Near the site is a spring. See Hebron.
