Tafsiran Bilangan 11:10: Rashi, Kli Yakar, Or HaChaim & Siftei Chakhamim

בכה למשפחתיו [THEN MOSES HEARD THE PEOPLE] WEEP THROUGHOUT THEIR FAMILIES — i.e. the members of each family gathered together and wept in order to display their discontent in public. Our Rabbis, however, said that למשפחתיו means “the people wept because of family affairs” — because of the intermarriage of blood-relaltives that had been forbidden to them (Sifrei Bamidbar 90; Yoma 75a).

“And Moses heard the people weeping by their families, each at the entrance of his tent.” For one cannot say that families gathered together in groups and wept, since it says each at the entrance of his tent. Rather, certainly [they were weeping] about matters of their families. And the anger of the Lord was kindled, and in Moses’ eyes it was bad. Specifically now [it was bad in Moses’ eyes], but before that it was bad only in the ears of the Lord, because Moses did not understand their intention. And regarding what it says, we remember [which refers to] the past, and that we would/will eat [nochal] which implies the future, this is what they said: that whenever we said in the past Let us appoint a leader and return to Egypt, at that time we remembered the fish that we will eat in the future when we arrive there. And regarding what it says free from the commandments, this will be explained, God willing, later in Parashat Pinchas (26:64), that they said this about tithes and offerings.

ויחר אף ה׳ מאד. G'd's anger was kindled very much. The reason why the Torah describes G'd's anger as מאד, "very much," is that people who fall victim to seduction by Satan have been victimised, in a sense. The same could not be said of the people described in our paragraph who had actually provoked the evil urge within themselves. There is no category of sin which is greater than that.
