Ad'dus a name twice occurring in the Apocrypha, but in both cases by interpolation.
1. (Α᾿δδούς, perhaps for Addon.) One of the "children of Solomon's servants," whose sons are said to have returned from Babylon (1 Esdras 5:34); but the genuine text (Ezr 2:51) has no such name.
2. (Ι᾿αδδού, as if for Jaddua.) A priest, after the captivity, who is said to have married a daughter of Berzelus, and hence assumed his name (1 Esdras 5:38); evidently a corruption for BARZILLAI (q.v.) of the genuine text (Ezr 2:61).
