(49) 1) Because G'd was aware of the dangers inherent in wealth, He provided Israel with bread from heaven on a day to day basis. This was to teach them the lesson that He was the great Provider, and that food serves specific objectives, that its accumulation is not an end in itself. Only in this way can one expect to be fed at "the two tables."
Tzedakah: The Untranslatable Virtue - Rabbi Jonathan Sacks
But mishpat alone cannot create a good society. To it must be added tzedakah, distributive justice. One can imagine a society which fastidiously observes the rule of law, and yet contains so much inequality that wealth is concentrated into the hands of the few, and many are left without the most basic requirements of a dignified existence. There may be high unemployment and widespread poverty. Some may live in palaces while others go homeless. That is not the kind of order that the Torah contemplates. There must be justice not only in how the law is applied, but also in how the means of existence – wealth as God’s blessing – are distributed. That is tzedakah.
Tzedakah cannot be translated because it joins together two concepts that in other languages are opposites, namely charity and justice. Suppose, for example, that I give someone $100. Either he is entitled to it, or he is not. If he is, then my act is a form of justice. If he is not, it is an act of charity. In English (as with the Latin terms caritas and iustitia) a gesture of charity cannot be an act of justice, nor can an act of justice be described as charity. Tzedakah is therefore an unusual term, because it means both. It arises from the theology of Judaism, which insists on the difference between possession and ownership. Ultimately, all things are owned by God, creator of the world. What we possess, we do not own – we merely hold it in trust for God. The clearest example is the provision in Leviticus: “The land must not be sold permanently because the land is Mine; you are merely strangers and temporary residents in relation to Me” (Leviticus 25:23).
