Deuteronomy 32:27 in the King James Version
Were it not that I feared the wrath of the enemy, lest their adversaries should behave themselves strangely, and lest they should say, Our hand is high, and the LORD hath not done all this.
Context
26 I said that I would scatter them afar. I would make their memory to cease from among men;
27 were it not that I feared the provocation of the enemy, lest their adversaries should judge wrongly, lest they should say, ‘Our hand is exalted; the LORD has not done all this.’”
28 For they are a nation void of counsel. There is no understanding in them.
