Isaiah 23:10 - Clarke's commentary and critical notes on the Bible

Pass through thy land as a river, O daughter of Tarshish: there is no more strength. O daughter of Tarshish - Tyre is called the daughter of Tarshish; perhaps because, Tyre being ruined, Tarshish was become the superior city, and might be considered as the metropolis of the Tyrian people; or rather because of the close connection and perpetual intercourse between them, according to that latitude of signification in which the Hebrews use the words son and daughter to express any sort of conjunction and dependence whatever. מזח mezach, a girdle, which collects, binds, and keeps together the loose raiment, when applied to a river, may mean a mound, mole, or artificial dam, which contains the waters and prevents them from spreading abroad. A city taken by siege and destroyed, whose walls are demolished, whose policy is dissolved, whose wealth is dissipated, whose people is scattered over the wide country, is compared to a river whose banks are broken down, and whose waters, let loose and overflowing all the neighboring plains, are wasted and lost. This may possibly be the meaning of this very obscure verse, of which I can find no other interpretation that is at all satisfactory. - L.
