Dân Số Ký 9:6

לפני משה ולפני אהרן [AND THERE WERE CERTAIN MEN, WHO … COULD NOT KEEP THE PASSOVER AND THEY CAME] BEFORE MOSES AND BEFORE AARON — At a time when both were sitting together in the House of Study they came and put this question to them. It would not be correct to say — as the words “”before Moses and before Aaron” might suggest — that they came to them one after the other, because if Moses did not know the reply whence could Aaron know it? (cf. Sifrei Bamidbar 68; Bava Batra 119b).

And there were certain men, who were defiled by the dead body of a man, that could not keep the passover on that day: and they came before Moshe and before Aharon on that day:

וַיְהִ֣י אֲנָשִׁ֗ים אֲשֶׁ֨ר הָי֤וּ טְמֵאִים֙ לְנֶ֣פֶשׁ אָדָ֔ם וְלֹא־יָכְל֥וּ לַעֲשֹׂת־הַפֶּ֖סַח בַּיּ֣וֹם הַה֑וּא וַֽיִּקְרְב֞וּ לִפְנֵ֥י מֹשֶׁ֛ה וְלִפְנֵ֥י אַהֲרֹ֖ן בַּיּ֥וֹם הַהֽוּא׃
