שְׁלִשִׁ֗ית בָּא֤וּר תַּבְעִיר֙ בְּת֣וֹךְ הָעִ֔יר כִּמְלֹ֖את יְמֵ֣י הַמָּצ֑וֹר וְלָֽקַחְתָּ֣ אֶת־הַשְּׁלִשִׁ֗ית תַּכֶּ֤ה בַחֶ֙רֶב֙ סְבִ֣יבוֹתֶ֔יהָ וְהַשְּׁלִשִׁית֙ תִּזְרֶ֣ה לָר֔וּחַ וְחֶ֖רֶב אָרִ֥יק אַחֲרֵיהֶֽם׃
Tu en feras brûler un tiers dans le feu au milieu de la ville, quand seront révolus les jours du siège; puis tu en prendras un tiers, que tu frapperas avec le glaive tout autour, et tu en disperseras un tiers au vent, et je tirerai le glaive derrière eux.
Rashi

Rashi

Rashi
