יָדַ֗עְתִּי כִּ֠י כָּל־אֲשֶׁ֨ר יַעֲשֶׂ֤ה הָאֱלֹהִים֙ ה֚וּא יִהְיֶ֣ה לְעוֹלָ֔ם עָלָיו֙ אֵ֣ין לְהוֹסִ֔יף וּמִמֶּ֖נּוּ אֵ֣ין לִגְרֹ֑עַ וְהָאֱלֹהִ֣ים עָשָׂ֔ה שֶׁיִּֽרְא֖וּ מִלְּפָנָֽיו׃
I know that, whatsoever God doeth, it shall be for ever; nothing can be added to it, nor any thing taken from it; and God hath so made it, that men should fear before Him.
