Elasa

ELASA ĕl’ ə sə (̓Ελασά), the place where Judas Maccabaeus lay encamped when Bacchides advanced upon him in 160 b.c. (1 Macc 9:5). In the ensuing battle, Judas was killed. The site is identified with Il’asa, near Beth-Horon.

Article 2

el’-a-sa, ele-a’sa (Alasa; the King James Version Eleasa):

The place where Judas pitched his camp before the battle in which he was overwhelmed and slain (APC 1Macc 9:5).

It probably corresponds to the modern Khirbet il`asa, between the two Beth-horons.
