"from the heavens": from the goodly treasure trove of the heavens, viz. (Devarim 28:12) "The L–rd will open for you His goodly treasure trove, the heavens, etc." R. Shimon b. Gamliel says: Come and see how beloved are Israel before the L–rd. And because they are thus beloved before Him, He changed for them the order of creation. He converted for them the terrestrial to the celestial, and the celestial to the terrestrial. In the past (before the giving of the manna), bread would rise from the earth and dew would fall from the heavens, viz. (Devarim 33:28) "… a land of corn and wine. His heavens, too, shall drip dew," and now (with the manna) the order has been reversed. Bread has begun to fall from heaven, and dew to rise from the earth, viz.: "Behold, I shall rain down bread for you from the heavens," and (Ibid. 14) "And, behold, the dew layer ascended, etc." (Ibid. 4) "and the people shall go out and gather": They did not gather it in the courtyards, but they went out to the wilderness and gathered it there.
