Methuselah (Mathusala or Mathusale)
Exact meaning is somewhat uncertain: Dr. Henry Morris said it may mean, “When he dies, judgment.” Others say: “When he is dead it shall be sent” (“it” refers to the Deluge) (Cornwall and Smith, Exhaustive Dictionary of Bible Names). Others say the name means: “Man of the dart” or “…javelin” (Holzinger / Also: Larry Richards, Every Man in the Bible.
He was the oldest man of whom we have any record. This very ancient man lived before the Flood, and died at the age of 969 years, in the year of the Flood (Gen. 5:21-27; 1 Chr. 1:3). This fact, plus the former possible meaning of his name, suggests that Methuselah's very godly father, Enoch, received a prophecy from God when his son was born, thus the name. Methuselah's great age may be further evidence of God's “long-suffering… in the days of Noah” (1 Peter 3:20; 2 Peter 3:9).
