Deuteronomy 32:27 KJV
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.
Deuteronomy 32:27, King James Version
In context
26 I said, I would scatter them into corners, I would make the remembrance of them to cease from among men:
27 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.
28 For they are a nation void of counsel, neither is there any understanding in them.
