Midrash sur Samuel 2 7:23

The Rabbis say: The Holy One blessed be He said to Moses: ‘Go and appoint a High Priest for Me.’ [Moses] said before Him: ‘Master of the universe, from which tribe?’ He said to him: ‘From the tribe of Levi.’ [Moses asked:] ‘With what will I anoint him?’ He said to him: ‘With the anointing oil.’ At that moment, Moses was joyful; he said: ‘My tribe is so beloved before the Holy One blessed be He.’ The Holy One blessed be He said to him: ‘By your life, it is not your tribe, but it is your brother’ – that is what is written: “And you, bring [Aaron your brother] near to you” (Exodus 28:1). His anointing with the anointing oil, from where is it derived? It is as it is stated: “You shall take the anointing oil […and anoint him]” (Exodus 29:7). However, his service is not service and he has liability unless the names of the tribes are engraved on his heart, as it is written: “Aaron will bear the names…[of the children of Israel…upon his heart]” (Exodus 28:29). The Holy One blessed be He said: ‘The names of the tribes are dearer to me than the anointing oil with which priests and kings are anointed.’
Rabbi Neḥemya said: The Holy One blessed be He said to Moses: ‘Go and appoint a High Priest for Me.’ [Moses] said before Him: ‘Master of the universe, from which tribe?’ He said to him: ‘From the tribe of Levi.’ [Moses asked:] ‘With what will I anoint him?’ He said to him: ‘With the anointing oil.’ At that moment, Moses was joyful; he said: ‘My tribe is so beloved before the Holy One blessed be He.’ The Holy One blessed be He said to him: ‘By your life, it is not your tribe, but it is your brother; that is what is written: “And you, bring [Aaron your brother] near to you” (Exodus 28:1). His anointing with the anointing oil, from where is it derived? It is as it is stated: “You shall take the anointing oil […and anoint him]” (Exodus 29:7). However, his service is not service and he has liability unless the names of the tribes are engraved on his two shoulders, as it is written: “Aaron shall bear their names before the Lord upon his two shoulders as a remembrance” (Exodus 28:12). “Six of their names [on one stone and the names of the six that remain on the other stone]” (Exodus 28:10). Rav Beivai said: Had they been missing one letter they would not have served their purpose. Rabbi Oshaya taught: Even one dot.
Rabbi Shimon ben Yoḥai taught: There are three crowns; the crown of Torah, the crown of priesthood, and the crown of kingship. The crown of priesthood, Aaron merited it and took it. The crown of kingship, David merited it and took it. The crown of Torah is available for [all] generations. Anyone who acquires Torah it is as though he acquired [all] three of them. Anyone who did not acquire Torah, it is as though he did not acquire any of them.
Rabbi Bon said in the name of Rabbi Shmuel bar Naḥmani: We found that the Holy One blessed be He went a distance that takes five hundred years to traverse to make a name for Himself, as it is written: “[Who is like Your people, like Israel…] whom God went to redeem to Himself for a people and to make a name for Himself […nations and their gods]” (II Samuel 7:23). Rabbi Yosei HaGelili said: A nation and its gods.⁷He interprets the end of the verse to mean that God redeemed Israel despite the fact that there were idolaters among them who took their gods with them. Rabbi Akiva said to him: You have rendered the sacred profane. The Israelites said before the Holy One blessed be He: ‘You redeemed Yourself, as it were, as it is stated: “Whom You redeemed for Yourself from Egypt, nations and their God”’ (II Samuel 7:23).⁸According to Rabbi Yosei HaGelili, this would be translated as “their gods.” It is written: “Whom God went [halakh] [to redeem] for Himself [a people]” (I Chronicles 17:21), and later it says: “Whom God went [halekhu] [to redeem for Himself for a people]” (II Samuel 7:23). Halakh, this is the Holy One blessed be He; halekhu, this is Moses and Aaron.⁹The term halekhu is plural, and therefore the midrash interprets it as referring to Moses and Aaron. Thus, the verse means that Moses and Aaron were emissaries God sent to accomplish this objective.

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."

(Exodus 15:2) "The L rd is my strength and my song": "My strength" is Torah, viz. (Psalms 29:11) "The L rd will give strength to His people," and it is written (Ibid. 99:4) "And (they will praise) the strength of the King, who loves (the Torah of) justice." Variantly: "My strength" is kingship, viz. (Ibid. 21:2) "O L rd, in Your strength the king rejoices," and (I Samuel 2:10) "And He will give strength to His king." Variantly: "My strength" is "My stronghold," as it is written (Jeremiah 16:19) "The L rd is my strength and my stronghold." And (Psalms 28:7) "The L rd is my strength and my shield. In Him does my heart trust, and I was helped, etc." You are a trust, a help, and a support to all who enter the world — but to me (David) more than to all. He made me distinct and I made Him distinct. He made me distinct — (Devarim 26:18) "And the L rd made you distinct unto Him this day )to be unto Him His chosen people.") And I, likewise, made Him distinct — (Ibid. 17) "You have made the L rd distinct this day to be unto you a G d." All the peoples of the world declare the praises of the Holy One Blessed be He, but mine are more pleasing before Him than theirs. As it is written (II Samuel 23:1) "And these are the last words of David: The utterance of David, the son of Yishai, and the utterance of the man set on high, the anointed of the G d of Yaakov, the fairest of the songs of Israel": Israel says (Devarim 6:4) "Hear, O Israel, the L rd our G d, the L rd is one," and the Holy Spirit cries out and says (Ibid. 33:29) "Happy are you, Israel! Who is like you, etc.?" Israel says (Ibid. 4:7) "Who … is like the L rd our G d in all our calling unto Him? And the Holy Spirit cries out and says (Ibid.) "And who is a great nation" ("that has G d near to it!") Israel says (Psalms 89:18) "For You are the glory of their strength, etc." And the Holy Spirit cries out and says (Isaiah 49:3) "Israel, in whom I glory!" (Exodus, Ibid.) "and He was a salvation unto me": You are a salvation unto all who enter the world, but unto me, more so. Variantly: "and He was a salvation unto me" — in the past, and thus will He be in the future.
