According to the Bible, Methuselah was the longest-lived person. He is mentioned in the book of Genesis, specifically in Genesis 5:27, which states: "So all the days of Methuselah were nine hundred and sixty-nine years, and he died."
Methuselah was the son of Enoch and the grandfather of Noah, who built the ark to survive the great flood. The Bible records that several individuals in the genealogy before the flood lived for extraordinarily long lifespans, but Methuselah holds the record as the longest-lived person mentioned in the biblical texts.
