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.
Jewish Publication Society of America Version (JPS1917) - Isaiah 47:11 >Yet shall evil came upon thee; thou shalt not know how to charm it away; and calamity shall fall upon thee; thou shalt not be able to put it away; and ruin shall come upon thee suddenly, before thou knowest.
