Since Jews are supposed to derive their origins from Shem, the name Semitic has been used to refer to them. The Children of Shem were Elam, Asshur, Aram, Arpachshad and Lud, in addition to daughters. In the New Testament, Jesus is listed as having been descended from Shem in an unbroken line through Abraham and David.
Terms like "Shemites" and "sons" of an eponymous "father" in general, are not supported outside of religious studies by modern historical scholarship. In the Ancient Near East (and in the Aegean), the earliest attempts at arriving at an Ethnology that would explain the contemporary sense that there were relative similarities and differences among neighboring or distant tribes, was expressed in terms of Genealogy; an approach reflected in terms like "Semite" and "Hamite". Neither "Semite" nor "Hamite" are broadly used now, and are sometimes perceived as offensive, because of their "racial" connotations.
However, the adjectival forms "Semitic" and "Hamitic," are more accepted, though the vague term 'Hamitic' dropped out of mainstream academic use in the 1960s. "Semitic" remains an indispensable technical term for, in particular, the Semitic languages, as a subset of the Afro-Asiatic languages, which show the common linguistic heritage of Hebrew, Arabic, Aramaic, Phoenician, Akkadian, and Ethiopic languages.
Semitic is also used in the fixed phrase "anti-Semitic" to refer to racial, ethnic or cultural prejudice towards Jews, and sometimes more generally including Arabs.
