Tossefta sur La Genèse 7:10

When the righteous come into the world, good comes into the world [with them], and divine retribution is removed from the world, and when they pass away from the world, divine retribution comes into the world, and good is removed from the world. When the evildoers come into the world, divine retribution comes into the world [with them], and good is removed from the world, and when they are removed from the world (i.e., when they die), good comes to the world and divine retribution is removed from the world. And from where is it derived that when the righteous come into the world, good comes into the world [with them] and divine retribution is removed from the world? As it is said (Gen. 5:29^*Note: Tanakh translations in this chapter generally follow JPS, 1985), "And [Lemekh] called his name Noah, saying, this one will bring us comfort from our labors, [from the ... ground, which God has cursed]." And from where is it derived that when they pass away from the world, divine retribution comes into the world and good is removed from the world? As it is said (Is. 57:1), "A righteous person perishes, and no one considers [... that because of evil the righteous one was taken away]," and it says (Is. 57:3) "But as for you, come closer, you children of a sorceress, you offspring of an adulterer, etc." And from where is it derived that when the evildoers come into the world, divine retribution comes to the world [with them] and good is removed from the world? As it is said (Prov. 18:3), "With the wicked man comes derision [and with the rogue, contempt]." And from where is it derived that when [the evildoers] are removed from this world, good comes into the world and divine retribution is removed from the world? As it is said (Prov. 11:10), "And when the wicked perish there are shouts of joy," and it says (Deut. 13:18), "In order that the Lord may turn from His blazing anger [and show you compassion]." Whenever there are evildoers in the world, there is "blazing anger" in the world, [but] when they have perished from the world, blazing anger is removed from world. And it is not that the righteous suspend the world with their lives alone, but also with their deaths, as it is said (Gen. 7:10), "And it was on the seventh day that the waters of the Flood [came upon the earth]." And what was the good of those seven days? So that [during] those seven days, they could mourn over Methuselah the Righteous, which held back the divine punishment [of the Flood] from coming onto the earth, and thus it is said, "And it was on the seventh day..." Another version: What was the good of those seven days? It teaches that the Place gave them seven days even after the decree, on the possibility that they would repent. And [clearly] they did not did so, as it is said, "And it was on the seventh day..." Another version: "And it was on the seventh day" -- what was the good of those seven days? It teaches that the Place altered the Order of Creation during them, and the sun rose in the west and set in the east. And thus it is said, "And it was on the seventh day..." Another version: What was the good of those seven days? It teaches that the Place gave them seven days of food and drink, and they sat and they ate and they drank, and [in that way] he showed them a small taste (מעין) of the World [to Come]. And why all of this? So that they would see, and recognize, and know what they had lost.
