Midrash su Isaia 33:16

R. Chiya b. Abba, in the name of R. Jochanan, said: "It is written (Ib. 11, 4) Riches profit not in the day of wrath; but tzedaka (righteousness) delivereth from death; and (Ib. 10, 2) Treasures of wickedness profit nothing: but tzedaka delivereth from death." What do the two tzedakas mean? One, that it will save him from an unnatural death; the other, that it will save him from Gehenna." Which one speaks of Gehenna? The one in which the day of wrath is mentioned, as it is written (Zeph. 1, 15) A day of wrath is that day, referring to Gehenna. And what kind of tzedaka saves one from unnatural death? (Ib. b.) If he gives, and knows not to whom, and he who receives it knows not from whom he gets it. Giving and knowing not to whom, excludes the act of Mar Ukba. "The receiver does not know from whom," excludes the act of R. Abba. But how then shall one give charity? By giving through the charity collector. An objection was raised from the following Baraitha: What shall one do that he should have male children. R. Elazar says: "He should distribute his money among the poor." R. Joshua b. Karcha says: "He should make his wife joyful." And R. Eliezerb. Jacob said: "He shall not give a coin for the treasury of charity unless the treasurer is like unto R. Chanina b. Tradion." [Hence to a charity collector is not the best method?] The above Baraitha means also when the treasurer was of that kind. R. Abahu said: "Moses said before the Holy One, praised be He: 'Sovereign of the Universe, how may the horn of Israel be exalted?' To which he answered: 'You should take charity from every one of Israel who is to be counted (Ex. 30, 12).'" R. Abahu said again: "King Solomon b. David was questioned: 'How great is the power of charity?' And he answered: 'Go and see how David, my father, explained this (Ps. 112, 9) He distributeth , he giveth to the needy: his righteousness endureth forever, his horn shall be exalted in honor.'" Raba, however, said from the following passage (Is. 33, 16) He shall dwell on high; rocky strongholds shall be his refuge; his bread shall be given him; his water shall be sure; i.e., why shall he dwell on high, etc.? Because he is sure that to the poor he has given his bread, and to the down-trodden his water."
