Person
Metushael מְתוּשָׁאֵל
fifth generation from Adam in Cain's line, father of Lemech
"And Mechuyael begot Metushael, and Metushael begot Lemech" (Bereshit 4:18).
His name is not to be confused with Metushelach of Seth's line, who lived nine hundred and sixty-nine years and died in the year of the Flood. The names are alike; the men and the lines are not.
The Torah gives no years.
