פָּנֹ֤ה אֶל־הַרְבֵּה֙ וְהִנֵּ֣ה לִמְעָ֔ט וַהֲבֵאתֶ֥ם הַבַּ֖יִת וְנָפַ֣חְתִּי ב֑וֹ יַ֣עַן מֶ֗ה נְאֻם֙ יְהוָ֣ה צְבָא֔וֹת יַ֗עַן בֵּיתִי֙ אֲשֶׁר־ה֣וּא חָרֵ֔ב וְאַתֶּ֥ם רָצִ֖ים אִ֥ישׁ לְבֵיתֽוֹ׃
Ye looked for much, and, lo, it came to little; and when ye brought it home, I did blow upon it. Why? saith the LORD of hosts. Because of My house that lieth waste, while ye run every man for his own house.
