Midrash sobre Job 3:13

When the earth heard this expression thereupon it trembled and quaked, crying before its Creator: Sovereign of all worlds ! I have not the power to feed the multitude of mankind. The Holy One, blessed be He, replied: I and thou will (together) feed the multitude of mankind. They agreed to divide (the task) between themselves: the night was for the Holy One, blessed be He, || and the day (was apportioned) to the earth. What did the Holy One, blessed be He, do? He created the sleep of life, so that man lies down and sleeps whilst He sustains him and heals him and (gives) him life and repose, as it is said, "I should have slept: then had I been at rest" (Job 3:13). The Holy One, blessed be He, supports (man) with the earth, giving it water; and it yields its fruit and food for all creatures—but the first man's food "in toil shalt thou eat of it all the days of thy life" (Gen. 3:17).

And Avraham perished (ibid.) - Rabbi Yehuda bar Ilai said, the original pious would suffer with intestinal disease for ten and twenty days, to say that illness clarifies. Rabbi Yehuda said, everyone of whom it is said "perish" died of intestinal disease. It's written, strength and beauty are her robes [and she laughs at the last day] (Mishlei 31:25) - every reward of the righteous is prepared for them for the future to come. The Holy Blessed One shows them, before they are in this world, all the reward which They will eventually give them in the world to come - and their souls are satisfied and they sleep. Rabbi Elazar says, it's like a banquet which a king prepared and invited guests, and showed them what they would eat and drink, and their souls are satisfied and they sleep - so too with the Holy Blessed One. They show the righteous before they are in this world their veentual reward, and they sleep, as it is said For now I would be lying down, silent (Iyov 3:13). That is to say, at the time of the departure of the righteous, the Holy Blessed One shows them the reward of their labour. When Rabbi Abahu slept, thirteen rivers of balsam were shown to him.
