Who was Methuselah?
In the Hebrew Bible or Christian Old Testament, Methuselah means "man of the javelin."
Methuselah was a descendant of Seth, the son of Enoch, and father of Lamech (Gen 5:21 ff; 1 Ch 1:3; Lk 3:37).
Methuselah is said to have lived 969 years; he is therefore the oldest of the patriarchs and the oldest man.
