THE NEW HEAVENS AND EARTH RABBAN GAMALIEL said: Just as the New Moons are renewed and sanctified in this world, so will Israel be sanctified and renewed in the future world just like the New Moons, as it is said, "Speak unto all the congregation of the children of Israel, and say unto them, Ye shall be holy: for I the Lord your God am holy" (Lev. 19:2). The sages say: The heavens and the earth are destined to pass away and to be renewed.
What is written concerning them? "And all the host of the heaven shall be dissolved, and the heavens shall be rolled together as a scroll" (Isa. 34:4). Just as when a man reads in a scroll of the Torah and he rolls it, and again he opens it to read therein and he rolls it (together), likewise in the future will the Holy One, blessed be He, roll together the heavens like a scroll, as it is said, "And the heavens shall be rolled together as a scroll" (ibid.); "And the earth shall wax old like a garment" (Isa. 51:6); just as a man spreads out his garment and folds it up, and again he unfolds it || and puts it on and renews it (thereby), likewise the Holy One, blessed be He, in the future will fold up the earth and again will He spread it out and put it in its place like a garment, as it is said. "And the earth shall wax old like a garment" (ibid.).
