אַ֣ף בַּל־נִטָּ֗עוּ אַ֚ף בַּל־זֹרָ֔עוּ אַ֛ף בַּל־שֹׁרֵ֥שׁ בָּאָ֖רֶץ גִּזְעָ֑ם וְגַם־נָשַׁ֤ף בָּהֶם֙ וַיִּבָ֔שׁוּ וּסְעָרָ֖ה כַּקַּ֥שׁ תִּשָּׂאֵֽם׃ (ס)
Scarce are they planted, Scarce are they sown, Scarce hath their stock taken root in the earth; When He bloweth upon them, they wither, And the whirlwind taketh them away as stubble.
Read halakhic rulings (Jewish law) on Isaiah 40:24: and classical halakhic sources.
