(Heb. Adin’, עָדַין , effeminate, as in Isaiah 47:8; Sept. Ἀδίν, Ἀδδίν , ᾿Ηδίν, ᾿Ηδείν ), the head of one of the Israelitish families, of which a large number (454, according to Ezra 2:15, but 655, according to Nehemiah 7:20 — the discrepancy being occasioned by an error in the hundreds, and the including or excluding of himself) returned from Babylon with Zerubbabel (B.C. 536) and fifty more (with Ebed the son of Jonathan) under Ezra (B.C. 459, Ezra 8:6). He appears to have been the same with one of those who subscribed the religious covenant with Nehemiah (Nehemiah 10:16, B.C. cir. 410). His name occurs in the parallel passages of the Apocrypha (Ἀδινού, 1 Esdras 5:14; Ἀδίν , 1 Esdras 8:32).
