Letu'shim (Heb. Letushiim', לטוּשַׁים , hammered, plur.; Sept. Λατουσιείμ), the second named of the three sons of Dedan (grandson of Abraham by Keturah), and head of an Arabian tribe descended from him (Ge 30:3; and Vulg. at 1Ch 1:32). B.C. considerably post 2024. SEE ARABIA. "Fresnel (Journ. Asiat. 3e serie, 6:217) identifies it with Tasm, one of the ancient and extinct tribes of Arabia, just as he compares Leummim with Umeiyim. The names may perhaps be regarded as commencing with the article. Nevertheless, the identification in each case seems to be quite untenable. It is noteworthy that the three sons of the Keturahite Dedan are named in the plural form, evidently as tribes descended from him" (Smith). "Forster supposes (Geor. of Arabia, 1:334) that the Letushim were absorbed in the generic appellation of Dedanim (Jer 25:23; Eze 25:13; Isa 21:13), and that they dwelt in the desert eastward of Edom."
