וַיֹּ֨אמֶר יְהוָ֜ה אֶל־מֹשֶׁ֗ה וְאָבִ֙יהָ֙ יָרֹ֤ק יָרַק֙ בְּפָנֶ֔יהָ הֲלֹ֥א תִכָּלֵ֖ם שִׁבְעַ֣ת יָמִ֑ים תִּסָּגֵ֞ר שִׁבְעַ֤ת יָמִים֙ מִח֣וּץ לַֽמַּחֲנֶ֔ה וְאַחַ֖ר תֵּאָסֵֽף׃
永恆者對摩西說：「即使是她父親吐唾沫在她臉上，她豈不也要羞愧七天嗎？現在要把她關在營外七天，然後才可以讓她回到營中。」
Shenei Luchot HaBerit
Yalkut Shimoni item 177 on Exodus 6,12, where we have another instance in which Moses uses the word לאמור when speaking to G–d, says that there are altogether four such instances. Rabbi Eleazar ben Azaryah claims that Moses demanded that G–d reply to him, i.e. “לאמור, whether He would redeem the Children of Israel or not. G–d responded in Exodus 6,1: "Now you will see what I shall do to Pharaoh, etc." A similar incident occurred when the Torah reported Moses as using this expression in Numbers 12,13 when he wanted an immediate answer whether G–d was going to heal Miriam or not. There, too, G–d is reported as responding to this outcry in verse 14, indicating that Miriam would be healed after a week. We also have such an instance in Numbers 27,15 where Moses wanted a reply from G–d to his request that He appoint a suitable leader in his stead. G–d responded in verse 18 that Joshua would be the new leader of the people. Lastly, the Yakut quotes the verse in our portion where Moses supposedly demanded an immediate response to his request to enter ארץ ישראל.
