וָֽאֶתְנַפַּ֞ל לִפְנֵ֣י יְהוָ֗ה אֵ֣ת אַרְבָּעִ֥ים הַיּ֛וֹם וְאֶת־אַרְבָּעִ֥ים הַלַּ֖יְלָה אֲשֶׁ֣ר הִתְנַפָּ֑לְתִּי כִּֽי־אָמַ֥ר יְהוָ֖ה לְהַשְׁמִ֥יד אֶתְכֶֽם׃
我在永恆者面前俯伏，就是我俯伏的那四十晝夜；因為永恆者說過要消滅你們。
Berakhot
Our Rabbis have taught : It happened that a disciple who descended before the Ark in the presence of R. Eliezer unduly prolonged [the prayers]. His disciples said to him, "Our master, what a prolonger he is!" He replied, "Did he prolong more than Moses, our teacher, of whom it is written, 'The forty days and forty nights that I fell down'" (Deut. ix. 25)?
