A city of the shephelah or lowland of Judah (Joshua 15:34). In Genesis 38:14; Genesis 38:21, read as margin "in the gate (phathach ) of Enaim," instead of "in an open place." It lay on the road from Judah's dwelling place to Timnath. Aben Ezra less probably translates "at the breaking forth of two fountains." Conder identifies it with Allin, a ruin close to Thamna, now Tibneh, three miles to the E. on an ancient road from Adullam, the very road by which Judah would have come from Adullain to Timnah. The fellahin dialect changes "n" into "l".
