Wiki Details
Methuselah (US: ; Hebrew: מְתוּשֶׁלַח Məṯūšélaḥ, in pausa מְתוּשָׁלַח Məṯūšālaḥ, 'his death shall send' or 'man of the javelin' or 'death of sword'; Greek: Μαθουσάλας Mathousalas) was a biblical patriarch and a figure in Judaism, Christianity, and Islam. He is claimed to have lived the longest life, dying at 969 years of age. According to the Book of Genesis, Methuselah was the son of Enoch, the father of Lamech, and the grandfather of Noah. Elsewhere in the Bible, Methuselah is mentioned in genealogies in 1 Chronicles and the Gospel of Luke.
His life is described in further detail in other texts such as the Book of Enoch, Slavonic Enoch, and the Book of Moses (although most Christians do not accept these books as canon). Bible commentators have offered various explanations as to why the Book of Genesis describes him as having died at such an advanced age: myth, mistranslation, or giving the impression that part of Genesis takes place in a very distant past. Methuselah's name has become synonymous with longevity, and he has been portrayed and referenced in film, television and music.
