Ad'don (Heb. Addon', אִדּוֹן, low or lord, or perhaps i. q. Iddo; Sept. ᾿Ηρών), the second of three persons mentioned in Ne 7:61, who, on returning from the captivity to Palestine, were unable to "show their father's house or their seed, whether they were of Israel," B.C. 536. This probably means that they were unable to furnish such undeniable legal proof as was required in such cases. And this is in some degree explained by the subsequent (verse 63) mention of priests who were expelled the priesthood because their descent was not found to be genealogically registered. These instances show the importance which was attached to their genealogies by the Jews. SEE GENEALOGY. In Ezr 2:59, he is called ADDAN SEE ADDAN , but in 1 Esdras 5:36, his name is contained in CHARA-ATHALAR SEE CHARA-ATHALAR . According to others, this is the name of a place in the land of the captivity, like Tel-melah and Tel-haresha preceding; but the names Cherub and Immer immediately adjoining appear to be those of men, and the Masoretic punctuation rather favors the distinction of these three names as residents of the two places just named.
