ISA 50:11

11 See, all ye that kindle an eish [(fire)], ye that prepare for battle with zikot [(flashing firebrands)], walk in the light of the fire of your [[own making]] and among the zikot [(flashing firebrands)] that ye have set burning, and this shall ye have from My Yad; ye shall lie down in ma'atze'vah [(torment, pain, grieving)].
