Musar su Salmi 112:9

A gift in the right place is a treasure put aside. It perisheth not in the course of time, but abideth with the ages. This is the opinion of Solomon, peace be upon him, who said (Eccl. xi. i), "Cast thy bread upon the waters; for thou shalt find it after many days." This verse evidently exhorts to generosity, for if man be generous and bountiful, he will reap the fruit thereof. Thus spake the poet: "Sow thou generosity in the field of gifts, and noble deeds shall be harvested by thee early." Wherefore man ought to know that if he be in a prosperous condition, then his generosity will not impair his prosperity, and if he be in a straitened condition, his adversity will not continue on that account. It is peculiar to this noble quality, that he who employs it never feels the want of anything; on the contrary, his abundance is much increased. Thus it is said (Prov. xxviii. 27): "He that giveth unto the poor shall not lack." Furthermore, David the Saint, peace be upon him, says of generous and liberal men (Ps. cxii. 9), "He hath dispersed, he hath given to the poor: his righteousness endureth forever." What is your opinion with reference to the use of this gracious virtue? It is like lending unto God, exalted and magnified is He. Thus the saying (Prov. xix. 17), "He that hath pity upon the poor lendeth unto the Lord." Thus it was said in the book on Ethics: "Bestow kindness on those who are worthy and upon those who are unworthy. In the case of the worthy, thy kindness will be in the right place; and in the case of the unworthy, prove thou thy worth." Again it was said with reference to liberality, "It is a part of the noble qualities to give liberally to him who asks."

By following this approach we can also understand the Midrash in Eichah Rabbati, 2,6, on Lamentations 2,3: "He has cut down in blazing anger כל קרן ישראל, all the might of Israel." The Midrash comments that there are ten קרנות, i.e. "strongholds" termed Keren. Abraham is one such קרן; he is referred to in Isaiah 5,1, as כרם היה לידידי בקרן בן שמן, "My beloved had a vineyard on a fruitful hill." Isaac is also known as a קרן, in Genesis 22,13 נאחז בסבך בקרניו, "caught in the thicket by its horns." We find a reference to Joseph as קרן in Deut. 33,17 where his קרן is described as וקרני ראם קרניו וכו' "He has thorns like the horns of a wild ox." Moses is referred to as קרן in Exodus 34,29: כי קרן עור פניו, "for the skin of his face emitted rays (like a horn)." The Torah is also described as קרן, since we read in Chabakuk 3,4: קרנים מידו לו, "it gives off rays of light in every direction." Priesthood is referred to as קרן, in Psalms 112,9, קרנו תרום בכבוד, "his horn is exalted in honor." (Possibly the word כבוד, used here which is also used in connection with the garments of the High Priest, is the reason the Midrash interprets this verse as alluding to the priesthood.) The Levites collectively are referred to as קרן in Chronicles 1 25,5: כל אלה בנים להימן חוזה המלך בדברי האלוקים להרים קרן. [The chapter traces the genealogy of the tribe of Levi Ed.] Prophecy is called קרן, in Samuel I 2,6: רמה קרני בה'. (Hannah prophesies about Samuel's future). The Holy Temple is also described as קרן, as in Psalms 22,22: מקרני רמים עניתני. Israel itself is also described as קרן in Psalms 148,14: וירם קרן לעמו. Some people add that the קרן of the Messiah should also be included, per Samuel I 2,10: ויתן עוז למלכו, וירם קרן משיחו. The Midrash continues that all of these "horns" were placed on the heads of the Jewish people, but they forfeited them due to their sins. This is alluded to in the verse we quoted earlier from Lamentations 2,3 that in His blazing anger G–d cut down every קרן of Israel. These "horns" subsequently were given to the Gentile nations, as is written in Daniel 7,20: ועל קרניא עשר די בראשה ואחרי די סלקת ונפלו מן קדמיה. "About the ten horns which were on its head, and the other one which came and fell." In verse 24 of the same chapter Daniel speaks about ten kings and kingdoms arising from the fallen horns. Provided Israel repents, G–d will restore these horns to their rightful place viz. Psalms 75,11: "And I will cut off all the horns of the wicked, but the horns of the righteous will be lifted up." This refers to the horns that the “Righteous One of the world,” i.e. G–d, had cut off. When is the time that He will restore them to their righful position? It is when G–d will raise the horn of His anointed: "He will raise the horn of His anointed" (Samuel I 2,10). Thus far the Midrash in Eychah Rabbati.

Know, that a gift in the right circumstances, for example, alms to the poor who revere God — is a treasure which is stored up and will never be lost but will remain forever. This was the intent of King Solomon, when he said, "Cast thy bread upon the waters, for thou shalt find it after many days" (Eccl. 11:1). The verse refers literally to generosity : he who sows charity will reap its products, and he who has this quality will prosper. As it is said, "There is that scattereth, and yet increaseth" (Prov. 11:24). It is also written, "He that giveth unto the poor shall not lack" (Prov. 28:27). David said concerning generous men, "He hath given to the needy; his righteousness endureth forever" (Ps. 112:9).
