וַיִּקְצֹ֣ף מֹשֶׁ֔ה עַ֖ל פְּקוּדֵ֣י הֶחָ֑יִל שָׂרֵ֤י הָאֲלָפִים֙ וְשָׂרֵ֣י הַמֵּא֔וֹת הַבָּאִ֖ים מִצְּבָ֥א הַמִּלְחָמָֽה׃
Ale rozgniewał się Mojżesz na wodzów wojska, tysiączników i setników, którzy wrócili z wyprawy wojennej;
Rashi on Numbers
ויקצף משה על פקודי החיל AND MOSES WAS ANGRY WITH THE פקודי החיל — WITH THOSE APPOINTED OVER THE ARMY — This serves to teach you that every misdeed of a generation is attributed to the leaders since these have the power to protest (Sifrei Bamidbar 157:5).
Tur HaArokh
ויקצוף על פקודי החיל, “He was angry at the commanders of the troops.” He did not display anger at Pinchas seeing that Hashem Himself had granted him the covenant of peace.
