Caleb, sometimes transliterated as Kaleb (כָּלֵב, Kalev; Tiberian vocalization: Kālēḇ; Hebrew Academy: Kalev) is a figure who appears in the Hebrew Bible as a representative of the Tribe of Judah during the Israelites' journey to the Promised Land. A reference to him may also be found in the Quran, although his name is not mentioned.
According to the Jewish Encyclopedia, "since "Caleb" signifies dog, it has been thought that the dog was the totem of [Caleb's] clan".Strong's Concordance states that "Caleb" is "perhaps a form of keleb (Hebrew: כָּ֫לֶב), meaning "dog", or else from the same root in the sense of "forcible", whereas the New American Standard Exhaustive Concordance states that keleb is of "uncertain derivation".
The original Hebrew name is pronounced /ˈkɑːlɛb/ or /ˈkɑːlɛv/; the modern English pronunciation /ˈkeɪləb/ is courtesy of the Great Vowel Shift.
