חָרַ֤שׁ בַּרְזֶל֙ מַֽעֲצָ֔ד וּפָעַל֙ בַּפֶּחָ֔ם וּבַמַּקָּב֖וֹת יִצְּרֵ֑הוּ וַיִּפְעָלֵ֙הוּ֙ בִּזְר֣וֹעַ כֹּח֔וֹ גַּם־רָעֵב֙ וְאֵ֣ין כֹּ֔חַ לֹא־שָׁ֥תָה מַ֖יִם וַיִּיעָֽף׃
The smith maketh an axe, And worketh in the coals, and fashioneth it with hammers, And worketh it with his strong arm; Yea, he is hungry, and his strength faileth; He drinketh no water, and is faint.
