Isaiah 47:11 in the World English Bible
Therefore disaster will come on you. You won’t know when it dawns. Mischief will fall on you. You won’t be able to put it away. Desolation will come on you suddenly, which you don’t understand.

12 Stand now with thine enchantments, and with the multitude of thy sorceries, wherein thou hast laboured from thy youth; if so be thou shalt be able to profit, if so be thou mayest prevail.
