Aditha'im (Heb. Aditha'yim, עֲדַיתִיַם, double prey or double ornament; Sept. Α᾿διαθάϊμ, but some copies omit; Vulg. Adithaim), a town in the plain of Judah, mentioned between Sharaim and Gederah (Jos 15:36).
Eusebius (Onomast. s.v.) mentions two places of the name of Adatha (Α᾿δαθά, Jerome, Aditha and Adia), one near Gaza, and the other near Diospolis (Lydda); the former being commonly supposed to be the same with Adithaim, and the latter with Hadid; and probably corresponding respectively to the two places called Adida (q.v.) by Josephus. Schwarz (Palest. p. 102) accordingly thinks that Adithaim is represented by the modern village Eddis, 5 Eng. miles east of Gaza (comp. Robinson's Researches, 2, 370 sq.); but this is too far from the associated localities of the same group, SEE TRIBE,which require a position not far from Moneisin, a village with traces of antiquity, about 5 miles south of Ekron (Van de Velde, Memoir, p. 114).
