🔼The names Mash and Meshech in the Bible
In Genesis 10:23, Mash is listed as a son of Aram, who is a son of Shem, who is a son of Noah. In 1 Chronicles 1:17 the same genealogy occurs, although the various generations are now all listed as sons of Shem. And Mash is called משך (Meshech). Another man named Meshech is mentioned as a son of Japheth, who is another son of Noah (Genesis 10:2). He is mentioned about half a dozen times in the Bible, mostly along with Javan and Tubal, and it's clear that these are the names of nations rather than individuals (Psalm 120:5, Ezekiel 27:13). Older translations may have the ethnonym "the Moschi" in stead of Meshech.
🔼Etymology of the names Mash and Meshech
The name מש (Mash) does not occur as regular word in Hebrew, but it may be viewed as a contraction of the word מוש (mush), meaning depart or remove (or rather: מוש could be viewed as an expansion of an original מש):
But it may just as well be formed from the verb משה (masha), meaning to draw out:
As such the name Mash may even be related to the name Moses and mean Drawn Out, as Jones' Dictionary of Old Testament Proper Names proposes. Still, Mash is not called Moses but Meshech in 1 Chronicles 1:17.
The clearly related name Meshech comes from the verb משך (mashak), meaning to draw or drag:
Our name Meshech is identical to the noun משך (meshek), meaning a drawing out.
🔼Mash and Meshech meaning
For a meaning of the name Mash, Jones' Dictionary of Old Testament Proper Names reads Drawn Out and relates it to the verb משה (masha). The name Meshech, Jones relates to the verb משך (mashak) and translates it with Drawing Out. NOBSE Study Bible Name List does not translate Mash but reads Extend(ed), or Tall for Meshech.
