Parallel
Isaiah 47:11
Brenton's English Septuagint · Berean Standard Bible
And destruction shall come upon thee, and thou shalt not be aware; [there shall be] a pit, and thou shalt fall into it: and grief shall come upon thee, and thou shalt not be able to be clear; and destruction shall come suddenly upon thee, and thou shalt not know.
But disaster will come upon you; you will not know how to charm it away. A calamity will befall you that you will be unable to ward off. Devastation will happen to you suddenly and unexpectedly.
