Deuteronomy 32:27

לולי כעס אויב אגור WERE IT NOT THAT THE WRATH OF THE ENEMY WAS אגור — i.e. were it not that the wrath of the enemy were heaped up (אגור) against them to destroy them, and if he does overpower them and destroy them, he will attribute the greatness to himself and to his god, and he will not attribute it to Me. That is the meaning of what is stated immediately afterwords: פן ינכרו צרימו — i.e. lest they treat the matter as arising from a stranger (ינכרו) by attributing their power to a stranger (נכרי) to whom the greatness, however, does not actually belong, פן יאמרו ידינו רמה וגו׳ LEST THEY SHOULD SAY, OUR HAND IS EXALTED etc.

לוּלֵ֗י כַּ֤עַס אוֹיֵב֙ אָג֔וּר פֶּֽן־יְנַכְּר֖וּ צָרֵ֑ימוֹ        פֶּן־יֹֽאמְרוּ֙ יָדֵ֣נוּ רָ֔מָה וְלֹ֥א יְהֹוָ֖ה פָּעַ֥ל כׇּל־זֹֽאת׃        

were it not for the heaped up wrath of the enemy, lest their adversaries should misdeem, and lest they should say, Our hand is high, and the Lord has not done all this.
