The spelling of the word "Methusael" is derived from the Hebrew name "Metushelach." In the International Phonetic Alphabet (IPA), the pronunciation of "Methusael" is /mɛθjuːseɪl/. The first syllable "Meth" is pronounced with the "eh" vowel sound, followed by "joo" with a long "u" sound, "s" with an "eh" sound, "ay" with a long "a" sound, and "el" with an "ehl" sound. The name, mentioned in Genesis 5:21-27, belongs to one of the longest-lived characters in the Bible, reportedly living for 969 years.
The name "Methusael" does not have a clear etymology as it appears to be a compound name that is only mentioned once in the Bible. In the Book of Genesis (6:3), Methusael is listed as one of the descendants of Cain. However, the origin and meaning of the name are uncertain.
One possible interpretation is that "Methusael" is a combination of two elements: "Methus" and "ael". "Methus" could be related to the Hebrew word "metushelach", which is the name of a long-lived man in the Bible, Methuselah. The "ael" element may be derived from the Hebrew word "El", which means "God" or "divine".
However, due to the lack of additional information about the name and its context, its precise etymology remains uncertain.
