Word Origin for genesis
Old English Genesis, first book of the Pentateuch, from Latin genesis, adopted as title of first book of Old Testament in Vulgate, from Greek genesis "origin, creation, generation," from gignesthai "to be born," related to genos "race, birth, descent" (see genus). As such, it translated Hebrew bereshith, literally "in the beginning," which was the first word of the text, taken as its title. Extended sense of "origin, creation" first recorded in English c.1600.
