Jew is any person belonging to the worldwide group that constitutes, through descent or conversion, a continuation of the ancient Jewish people, who were themselves descendants of the Hebrews of the Bible (Old Testament). In ancient times, a Yĕhūdhī was originally a member of Judah—i.e., either of the tribe of Judah (one of the 12 tribes that took possession of the Promised Land) or of the subsequent Kingdom of Judah (in contrast to the rival Kingdom of Israel to the north). The Jewish people as a whole, initially called Hebrews (ʿIvrim), were known as Israelites (Yisreʾelim) from the time of their entrance into the Holy Land to the end of the Babylonian Exile (538 BCE). Thereafter, the term Yĕhūdhī (Latin: Judaeus; French: Juif; German: Jude; and English: Jew) was used to signify all adherents of Judaism, because the survivors of the Exile (former inhabitants of the Kingdom of Judah) were the only Israelites who had retained their distinctive identity. (The 10 tribes of the northern kingdom of Israel had been dispersed after the Assyrian conquest of 721 BCE and were gradually assimilated by other peoples.) The term Jew is thus derived through the Latin Judaeus and the Greek Ioudaios from the Hebrew Yĕhūdhī. The latter term is an adjective occurring only in the later parts of the Hebrew Bible and signifying a descendant of Yehudhah (Judah), the fourth son of Jacob, whose tribe, together with that of his half brother Benjamin, constituted the Kingdom of Judah.
