Isaiah 1:31

³¹And your strength shall be as a dead spark of stubble, either of hards of flax, and your work shall be as a quick spark; and ever either shall be burnt together, and none shall be that shall quench. (And your strength shall be like a dead spark of stubble, or of the husks of flax, and your work shall be like a living spark; and both shall be burned together, and no one shall be able to quench them.)
