Methuselah, in the Hebrew Bible (Old Testament), patriarch whose life span as recorded in Genesis (5:27) was 969 years. Methuselah has survived in legend and tradition as the longest-lived human. His prodigious age has been taken as literally 969 solar years, as a possible mistranslation of 969 lunar months or tenths of years (with his age then ranging from about 78 years to almost 97 years), and as a myth intended to create an impression of a distant past between Adam and Noah, as well as any number of other interpretations.
Genesis tells nothing about Methuselah beyond sparse genealogical details: according to Genesis 5, he was the great-great-great-great-grandson of Seth, the child of Adam and Eve begotten more than a century after Cain. He was the father of Lamech and the grandfather of Noah. According to the biblical account, he came of hardy stock: all his forebears lived to an age between 895 and 962 years except his father, Enoch, who lived to be 365. (In the genealogy of Cain in Genesis 4, there is a Methushael who also fathers a Lamech. Given this and certain other similarities, some scholars have proposed that the genealogies of Seth and Cain were possibly one list that became two at some point.)
The enumeration of Methuselah in Genesis is his only appearance in the Hebrew Bible save for a mention in 1 Chronicles 1:3, where he is cited in the lineage of Saul. In the New Testament he is mentioned once in the Gospel of Luke. There, at 3:23–38, the lineage of Joseph, husband of Mary and earthly father of Jesus, is traced back 75 generations, through David and Saul, and Abraham, Isaac, and Jacob, to Methuselah and thence to Seth and Adam.
