Talmud do Rodzaju 7:10

From where in the Torah that mourning is seven {days}? He organized seven days of mourning for his father¹⁹⁰Gen.50:10.. Can you infer anything from before the giving of the Torah¹⁹¹And in any case the mourning organized by Josef could not have followed Jewish rules.? Rebbi Jacob bar Aḥa in the name of Rebbi Ze`ira understood it from the following: At the door of the Tent of Meeting you shall sit day and night for seven days, and keep the watch of the Eternal’ s sanctuary¹⁹²Lev. 8:35, quoted incorrectly.. Just as the Holy One, praise to Him, watched over His World for seven {days}, so you shall watch for your brothers for seven {days}. And from where that the Holy One, praise to Him, watched over His World for seven {days}? It was after seven days that the Deluge came over the world¹⁹³Gen. 7:10. Gen. rabba 32(10).. May one mourn before the dying person dies? Only flesh and blood who do not know what will be in the future do not mourn until the dying person dies. But the Holy One, praise to Him, Who knows what will be in the future did first watch for His world. Some want to say, these are the seven days of mourning for Methusela the Just¹⁹⁴Gen. rabba 32(10), Babli Sanhedrin108b. Methusela had Lemekh when he was 187, Lemekh had Noe when he was 182, and the Flood was in Noe’s year 600, which was Methusela’s year 969, the year of his death.. Rebbi Hoshaia said, for the Eternal’s anointing oil is on you¹⁹⁵Lev. 10:7.. Just as you were anointed with the anointing oil all of seven, so watch for your brothers all of seven. Rebbi Abbahu in the name of Rebbi Joḥanan: please let her not be like the dead¹⁹⁶Num. 12:12.. She shall be locked away¹⁹⁷Num. 12:14.. Just as the day of isolation for the dead are seven, so the days of quarantine are seven. One student reported this from Rebbi Joḥanan before Rebbi Simeon ben Laqish, who did not accept it. He said, here he¹⁹⁸R. Joḥanan accepts two contradictory explanations of one and the same verse. uses it for isolation, but there he uses it for making absolute, as Rebbi Joḥanan said in the name of Rebbi Yannai, please let her not be like the dead: just as the days of the dead are not counted, so the days of being absolute are not counted¹⁹⁹Since a nazir must be pure, a vow of nazir made when the person either was impure in the impurity of the dead or having been declared absolutely impure in the impurity of skin disease is suspended until the person becomes pure. Only then may he start counting the thirty days of his vow. Babli Nazir 56a.. Rebbi Jeremiah and Rebbi Ḥiyya in the name of Rebbi Simeon ben Laqish; Rebbi Abbahu, Rebbi Yose ben Ḥanina in the name of Rebbi Simeon ben Laqish: the days of crying of the mourning for Moses ended²⁰⁰Deut. 34:8. Gen. rabba 100(7).. “The days”, seven. “Of crying”, two. “Mourning”, thirty²⁰¹The duration of standard mourning.. Some switch, “the days”, two, “of crying”, seven, “mourning”, thirty. Rebbi Yose, Rebbi Ḥiyya, and Rebbi Simeon ben Laqish in the name of Rebbi Judah the Patriarch: I shall turn your holiday into mourning²⁰²Am. 8:10. There is no proof from the Torah.. Since the days of Tabernacles are seven, also the days of mourning are seven. Rebbi Immi said to Rebbi Ḥiyya bar Abba: Maybe since the days of Tabernacles are eight²⁰³And חג, biblically “holiday of pilgrim-age”, in Mishnaic Hebrew means “Tabernacles.” Babli 20a., also the days of mourning are eight? He answered him, the eighth day is a separate holiday²⁰⁴Ḥagigah 1:6, Note 151. Or since Pentecost is one day, also mourning is one day? He answered him, from here about a deferred information²⁰⁵When a relative is informed of a death long after it occurred and he has to observe some signs of mourning at that time only. Babli 20a.. And it was stated such: Current information requires Seven and Thirty. Deferred information does not require Seven and Thirty.

There were ten generations from Adam until Noah.
And why was it necessary to bring all those people into the world? This teaches you that even as all those generations continued to anger the Holy Blessed One, He did not bring the flood upon them because of the righteous and saintly among them. And some say that as long as Methuselah was alive, the flood did not come upon the world; and even when Methuselah died, it was still held off for another seven days, as it says (Genesis 7:10), “And it was seven days, [and the waters of the flood were on the earth].” What was happening during those seven days? These were the [seven] days of mourning for that righteous man, who had prevented the punishment. That is why it says, “And it was seven days.”
Another interpretation of, “And it was seven days”: This teaches that the Holy Blessed One fixed a specific time, after 120 years, hoping that they might repent. But they did not, and so it says, “And it was seven days” [i.e., the final seven days of the countdown].
Another interpretation of, “And it was seven days”: This teaches that the Holy Blessed One changed the order of the world [which was created in seven days] for them, and had the sun rise from the west and set in the east, hoping that maybe they would understand and become afraid and repent. But they did not, and so it says, “And it was seven days.”
Another interpretation: This teaches that the Holy Blessed One set a table for them, and gave them a taste of the World to Come, so that they would gather together and say to one another, “Oy, for we have lost all this goodness, and we have caused the destruction of our descendants (from the earth), as it says (Genesis 6:12), “And God saw the earth, and it had been destroyed.”
