ALLAR (1Es_5:36).One of the leaders of those Jews who could not show their pedigree as Israelites at the return from captivity under Zerubbabel. The name seems to correspond to Immer in Ezr_2:59, Neh_7:61, one of the places from which these Jews returned. In 1 Es Cherub, Addan, and Immer appear as Charaathalan leading them and Allar.

al?ar (the King James Version, Aalar; Ἀαλάρ, Aalár): Occurring once (1 Esdras 5:36) and used apparently to indicate a place from which certain Jews came on the return from captivity, who could not prove their lineage, and were excluded for this reason from the privileges of the priesthood. HDB identifies with Immer of Ezr_2:59 and Neh_7:61 (which see), but this is not at all certain.
