Deuteronomy 32:25-27

Young's Literal Translation

²⁵ Without bereave doth the sword, And at the inner-chambers -- fear, Both youth and virgin, Suckling with man of grey hair.

²⁶ I have said: I blow them away, I cause their remembrance to cease from man;

²⁷ If not -- the anger of an enemy I fear, Lest their adversaries know -- Lest they say, Our hand is high, And Jehovah hath not wrought all this.
