Midrash su Salmi 89:18

(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.

(Ibid. 26) "There is none like the Almighty, Yeshurun": Israel says "There is none like G-d," and the Holy Spirit responds "like the G-d of Yeshurun" (Israel). Israel says (Shemoth 15:11) "Who is like You among the mighty, O L-rd," and the Holy Spirit responds (Devarim 33:29) "Happy are you, O Israel. Who is like you?" Israel says (Ibid. 6:4) "Hear, O Israel, the L-rd our G-d, the L-rd is one," and the Holy Spirit responds (I Chronicles 17:21) "Who is like Your people Israel?" Israel says (Song of Songs 2:3) "As an apple among the trees of the forest, (so is my Beloved"), and the Holy Spirit responds (Ibid. 2) "As a rose among the thorns, (so is My loved one"). Israel says (Shemoth 15:2) "This is my G-d and I will extol Him," and the Holy Spirit responds (Isaiah 43:21) "This people did I fashion for Myself." Israel says (Psalms 89:18) "For You are the splendor of their strength," and the Holy Spirit responds (Isaiah 49:3) "Israel, in whom I glory."
