Midrash su Geremia 40:3

We are taught in a Baraitha: Rabban Jochanan b. Zakkai said to his disciples: "My children, what is the meaning of the passage (Prov. 14, 34) Tzedaka exalteth a people; but the disgrace of nations is sin?" R. Eliezer responded and said: "Tzedakah exalteth a people, refers to Israel, as it is written (II Sam. 7, 23) And who is like Thy people, like Israel, the only nation on the earth; but the disgrace of nations is sin; i.e., all the tzedakah and kindness of the nations, if they indulge in them only for the purpose of becoming great or gaining a good name, is a sin for them, as it is said (Ezra 6, 10) That they may offer sacrifices of sweet savours unto the God of heaven, and pray for the life of the king and of his sons." R. Joshua responded and said: "Tzedaka exalteth a people, refers to Israel; but the disgrace of the nation is sin; i.e., all the tzedaka and kindness of the nations is sin, for they do so in order that their kingdom shall endure for a long time, as it is said (Dan. 4, 24) Therefore, O king, let my council be agreeable unto thee, and atone for thy sins by … perhaps thy prosperity may (thereby) endure long." Rabban Gamaliel responded and said: "Tzedaka exalteth a people, refers to Israel; but the disgrace of nations is sin; i.e., all the tzedaka and kindness of the nations is sin for the nations, because if they do, it is solely to boast of it to other nations. And whoever boasts of himself falls into Gehenna, as it is said (Prov. 21, 24) The presumptuous and proud, scorner is his name, who dealeth in the (ebra) wrath of presumption. Ebra (wrath) refers to Gehenna, for it is said (Zeph. 1, 15) A day of ehra (wrath) is that day." "For the right interpretation of this verse," remarked Rabban Gamaliel, "we are still in need of the Modite; for R. Eliezer the Modite, interpreted it thus: 'Tzedaka exalteth a people, refers to Israel; but the disgrace of nations is sin; i.e., all the tzedaka and kindness of the nation is only for the purpose of insulting Israel, as it is said (Jer. 40, 3) Now the Lord hath brought it ... ... ... because ye have sinned." etc. R. Nechunia b. Hakana, however, responded and said: "Tzedaka and kindness exalteth a nation, refers to Israel; to whom it is a grace as well, but to the nations it is considered a sin-offering." Rabban Jochanan b. Zakkai [the teacher] then rejoined: "It seems to me that Nechunia's interpretation is better than yours and mine." "Than min!" Did he also say something in connection with this? If so, then what is it? As we have been taught in a Baraitha: R. Jochanan b. Zakkai said: "As a sin-offering atones for Israel, so does charity atone for all other nations."
