Tobit is a given name derived from Greek Τωβίθ (Tobith), ultimately from Hebrew טוֹבִיה (Tovi), a possessive form meaning “my good,” rooted in the Hebrew element ṭov, meaning “good.” The name appears in the ancient Book of Tobit, a short novel included in the Old Testament by Catholic and Eastern Orthodox churches but considered apocryphal by Protestants and Judaism. Biblical Origins and Narrative The Book of Tobit recounts the story of Tobit, a pious Israelite exiled in Nineveh who becomes blind and suffers misfortune. He sends his son, Tobias (see Tobias), to Media to recover money, accompanied by the angel Raphael (see Raphael) disguised as a man. Raphael protects Tobias and later cures Tobit’s blindness. The tale is widely read for its themes of charity, prayer, and divine providence. Statistical Usage In modern statistics, the name “Tobit” also designates a regression model for censored data, coined in 1964 by A. S. Goldberg as a portmanteau of probit and economist James Tobin’s surname. Nonetheless, as a biblical name, Tobit is rare but continues to appear—often revived through Catholicism references to the scriptural figure. Related variants include Tobith (Biblical Greek) and Tovi (Biblical Hebrew). Though not widespread, the name remains a link to both ancient Hebrew onomastics and Deuterocanonical tradition.
