יְפַלֵּ֥ס נָתִ֗יב לְאַ֫פּ֥וֹ לֹא־חָשַׂ֣ךְ מִמָּ֣וֶת נַפְשָׁ֑ם וְ֝חַיָּתָ֗ם לַדֶּ֥בֶר הִסְגִּֽיר׃
Он выровнял путь для Своего гнева; Он не пощадил их душу от смерти, но отдал их жизнь на эпидемию;
Rashi on Psalms
He leveled a path for His anger Although the plagues were dispatched in anger, they performed only their orders; what they were commanded to kill, they killed, but nothing else. They went in their paths. In other commentaries I found as follows: He leveled a path for His anger When He smote every firstborn in Egypt, He showed the way for [the angel] who was destroying with anger to enter the houses of the Egyptians, but not the houses of the children of Israel.
