Isaiah 47:11

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.

Therefore shall evil come upon thee; thou shalt not know from whence it riseth: and mischief shall fall upon thee; thou shalt not be able to put it off: and desolation shall come upon thee suddenly, which thou shalt not know.

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.
