Thou shalt be hid from the scourge of the tongue (comp. Psalms 31:20). God will also protect his own from "the scourge of the tongue," i.e. from calumny, from abuse, from bitter words (see the comment on Job 5:15).
Neither shalt thou be afraid of destruction when it cometh; rather, of devastation. "Shod ( שׁוֹר) populationes, praedationes, calamitosas tempestates, terrae motus, ruinas, incendia, mala omnia vasti-tatem inducentia, amplectitur" (Schultens).
