אִם־יָצָ֣אתִי הַשָּׂדֶ֗ה וְהִנֵּה֙ חַלְלֵי־חֶ֔רֶב וְאִם֙ בָּ֣אתִי הָעִ֔יר וְהִנֵּ֖ה תַּחֲלוּאֵ֣י רָעָ֑ב כִּֽי־גַם־נָבִ֧יא גַם־כֹּהֵ֛ן סָחֲר֥וּ אֶל־אֶ֖רֶץ וְלֹ֥א יָדָֽעוּ׃ (ס)
If I go forth into the field, Then behold the slain with the sword! And if I enter into the city, Then behold them that are sick with famine! For both the prophet and the priest are gone about to a land, and knew it not.
