Mash in the Bible Encyclopedia - ISBE

(mash): Named in Gen 10:23 as one of the sons of Aramaic In the parallel passage in 1 Ch 1:17 the name is given as "Meshech" (meshekh), and the Septuagint (Mosoch) supports this form in both passages. "Meshech," however, is a Japhetic name (Gen 10:2), and "Mash" would seem to be the original reading. It is probably to be identified with the Mons Masius of classical writers (Strabo, etc.), on the northern boundary of Mesopotamia.
