CASLUHIM kăs’ lə hĭm (Heb. כַּסְלֻחִ֗ים; LXX Gr. Χασμωνιειμ), the name of an unidentified tribe sprung from Egypt, and the progenitor of the Philistines. It is placed in a class of tribes with the Anamim, Lehabim, Naphtuhim and Pathrusim, while after its offspring appears the Caphtorim usually thought to be the Cretans. The difficulty of the name and its now lost identification is clear from the large number of variants. An identification of this tribe with the Nasamonians of Herodotus, Histories, II, 32, et al. has not been widely supported. The Heb. name appears only twice (Gen 10:14 and 1 Chron 1:12).
