וַֽיְהִי־שָׁ֣ם עִם־יְהוָ֗ה אַרְבָּעִ֥ים יוֹם֙ וְאַרְבָּעִ֣ים לַ֔יְלָה לֶ֚חֶם לֹ֣א אָכַ֔ל וּמַ֖יִם לֹ֣א שָׁתָ֑ה וַיִּכְתֹּ֣ב עַל־הַלֻּחֹ֗ת אֵ֚ת דִּבְרֵ֣י הַבְּרִ֔ית עֲשֶׂ֖רֶת הַדְּבָרִֽים׃
And he was there with the LORD forty days and forty nights; he did neither eat bread, nor drink water. And he wrote upon the tables the words of the covenant, the ten words.
