Revelation 11:5-7

Young's Literal Translation

⁵ and if any one may will to injure them, fire doth proceed out of their mouth, and doth devour their enemies, and if any one may will to injure them, thus it behoveth him to be killed.

⁷ `And when they may finish their testimony, the beast that is coming up out of the abyss shall make war with them, and overcome them, and kill them,
