וְהָיָ֖ה בַּיּ֣וֹם הַה֑וּא אֲבַקֵּ֗שׁ לְהַשְׁמִיד֙ אֶת־כָּל־הַגּוֹיִ֔ם הַבָּאִ֖ים עַל־יְרוּשָׁלִָֽם׃
און עס װעט זײַן אין יענעם טאָג, װעל איך זוכן צו פֿאַרטיליקן אַלע פֿעלקער װאָס קומען אױף ירושָלַיִם.
Rashi
I will seek to destroy I will seek their destruction, and I will be exact in judging their iniquity. And our Sages (Avodah Zarah 4a) explained this verse as concerning merit. I will search in the books of their deeds; if they have merit, I will spare them; otherwise, I will destroy them.
