How was this a response to Moshe's request "Kel Na Refa Na Lah!"?
Rashi: Moshe asked Hashem to inform him whether He would answer him or not. 1 And Hashem replied in the affirmative, and that this is how He would cure her.
Seforno: Moshe asked Hashem whether, in order to spare Miriam the embarrassment, He would not cure her immediately without having to send her out of the Camp, to which Hashem replied that the embarrassment was an intrinsic part of her atonement. 2
Why did Hashem mention what Miriam's father would do?
Rashi: Because, if her father would have been angry with her, he would have placed her in quarantine for seven days, 1 in which case, now that the Shechinah was angry with her, she ought to be quarantined for 14 days. 2 And the reason that it was only seven was due to the principle 'Dayo l'Ba min ha'Din Lih'yos k'Nidun'. 3
What are the connotations of "Achar Te'asef"?
Rashi: Whenever the Torah uses the term 'Asifah' in connection with Metzora'im, it always has connotations of being gathered back into the camp.
Why did the Shechinah, the camp of Yisrael, the Aron and all of Yisrael delay seven days for Miriam to be cured?
Targum Yonasan: On the merit of Moshe 1 (whose honor had been wounded).
Rashi writes that if her father were angry with her, she would be shut up for seven days. Why should she be shut up for 14 for angering the Shechinah?
Moshav Zekenim #1: Once she will be shut up for more than seven, she needs another seven, for Hesger is not less than seven days. 3
Moshav Zekenim #2: A day of Hashem is like 1000 years. The Torah said 14, for after she two weeks of Hesger she becomes Muchlat, and is Tamei forever.
Moshav Zekenim citing Rivam citing a Midrash. Moshe is called 'Shechinah' 4 :
'Fourteen' is not precise. It means, more than we find through Hesgerim, for a Metzora is Musgar at most twice, i.e. 13 days, since the seventh day counts [as a full day] for both Hesgerim. (Perhaps this is the answer that Da'as Zekenim and Hadar Zekenim bring from R. Baruch
Rosh: From logic, we would say that angering the Shechinah is millions of times more severe! Hashem pardons His honor to those who fear Him.
Moshav Zekenim: Hashem contributes as many as the father and mother combined (also for angering her mother, she should be shut up for seven days).
Moshav Zekenim: Riva rejected this, for two weeks of Hesger is only 13 days, since the seventh day counts [as a full day] for both Hesgerim.
He did not explain why she should be shut up twice as much for Moshe as for her father.
Rashi writes that if her father were angry with her, she would be shut up for seven days, and if so, 14 for angering the Shechinah. Why don't we say about every Kal v'Chomer, that we should learn more than the source, according to the stringency?
Hadar Zekenim citing R. Aharon: If the Tzara'as remained for 14 days (two Hesgerim), she would be Muchlat and Tamei forever. 1
I do not understand this. Also a Muchlat can become Tahor after the Tzara'as goes away! (PF)
Rashi writes that if her father were angry with her, she would be shut up for seven days. What is the source for this?
Da'as Zekenim: A father being angry with her (Nezifah) is like Menudah, who is like an Avel, which is for seven days. 1
Da'as Zekenim: When Moshe was cast into the river, Amram thumped her on the head and said 'where is your prophecy [that my son will save Yisrael]?!' She stood "me'Rachok", like a Metzora, who is distanced for seven days. 2 In Mo'ed Katan (16a), we learn from "Tikalem Shiv'as Yamim" that Nezifah of Rabanan is seven days.
Da'as Zekenim: This is difficult, for the seven days of Aveilus are mid'Rabanan. Also her father was not alive at the time! We can say, if he were alive, she would be shut up for seven days. (What is the source that Amram was dead? Above, Da'as Zekenim connotes that he remarried after Matan Torah
