Enaim . A Jud¿an town in the Shephçlah (  Joshua 15:34 . ‘ Enam ’;   Genesis 38:14 , AV [Note: Authorized Version.] ‘in an open place,’ RV [Note: Revised Version.] ‘in the gate of Enaim’;   Genesis 38:21 , AV [Note: Authorized Version.] ‘openly,’ RV [Note: Revised Version.] ‘at Enaim’). From the narrative in   Genesis 38:1-30 we gather that it lay between Adullam and Timnah. The site is not identified. Conder suggests Khirbet Wâdy Alin , near Beth-shemesh and En-gannim.

ē̇ - nā´im ( עינים , ‛ēnayı̄m , "place of a fountain"; Αἰνάν , Ainán  ;  Genesis 38:14 (the King James Version "in an open place";   Genesis 38:21 the King James Version "openly")): A place which lay between Adullam and Timnath; probably the same as Enam (  Joshua 15:34 ). Also mentioned in close connection with Adullam. It was in the Shephelah of Judah. The Talmud ( Pesik̇ Rab . 23) mentions a Kephar Enaim. Conder proposes Khurbet Wady ‛Alı̂n , which is an ancient site, evidently of great strength and importance, lying between Kḣ ‛Ain Shems and the village of Deir Aban . The ruins crown a lofty and almost isolated hill; the greatest objection to the identification is that there is no fountain at all in the immediate neighborhood. There may have been one in earlier times. See PEF , III, 128.
