Midrash su Salmi 98:1

“I am a rose of Sharon, a lily of the valleys” (Song of Songs 2:1).
“I am a rose [ḥavatzelet] of Sharon.” The congregation of Israel said: I am as I am, yet I am beloved [ḥaviva]. It is I whom the Holy One blessed be He loved me more than seventy nations. “A rose [ḥavatzelet] of Sharon,” I made Him shelter [tzel] by means of Betzalel, as it is written: “Betzalel crafted the Ark” (Exodus 37:1). “Of Sharon,” as I recited song [shira] before Him by means of Moses, as it is written: “Then Moses and the children of Israel sang” (Exodus 15:1).
Another matter, “I am a rose of Sharon.” The congregation of Israel said: I am as I am, yet I am beloved. It is I who was shrouded in the shadow of Egypt, but the Holy One blessed be He brought me quickly to Rameses. I sprouted good deeds like a lily, and I recited a song before Him, as it is stated: “The song will be for you like the night of the consecration of the festival” (Isaiah 30:29).¹The song after the fall of Sennacherib will be like the Hallel that they recited in Egypt on the night before they left.
Another matter, “I am a rose of Sharon.” The congregation of Israel said: I am as I am, yet I am beloved. It is I who was shrouded in the shadow of the sea,²I was in danger when Pharaoh was pursuing me. but I quickly sprouted good deeds like a lily, and I pointed to Him with my finger [and pronounced that He is] my Master, as it is stated: “This is my God and I will exalt Him” (Exodus 15:2).
Another matter, “I am a rose of Sharon.” I am as I am, yet I am beloved. It is I who was shrouded in the shadow of Sinai.³God suspended the mountain over the Israelites, threatening to obliterate them if they refused to accept the Torah (see Shabbat 88a). I quickly blossomed good deeds with my hand and my heart, and I said before Him: “Everything that the Lord has spoken we will perform and we will heed” (Exodus 24:7).
Another matter, “I am a rose of Sharon.” I am as I am, yet I am beloved. It is I who was shrouded and trampled in the shadow of kingdoms. Tomorrow, when the Holy One blessed be He redeems me from the shadow of the kingdoms, I will blossom like a lily, and I will recite a new song before Him, as it is stated: “A psalm. Sing to the Lord a new song, for He has performed wonders; His right hand and His holy arm have wrought salvation for Him” (Psalms 98:1).

(Fol. 24b) (I Sam. 6, 12) (Vayisharna) And the cows went straight forward. What does the expression Vayisharna mean? Said R. Jochanan in the name of R. Mair: "They sang a song." And R. Zutra b. Tubiah, in the name of Rab, said: "They have straightened their faces to look upon the ark, and sang a song." What was their song? R. Jochanan in the name of R. Mair said (Ex. 15, 1) Then sang Moses, etc. R. Jochanan himself, however, said (Is. 12, 4) And ye shall say on that day, Give thanks unto the Lord, call on His name, etc. And R. Simon b. Lakish said: "The song the orphan chapter (a chapter in which the author's name is not mentioned) (Ps. 98, 1) Oh sing unto the Lord a new song; for He Hath done marvelous things, etc." And R. Elazar said (Ib. 99, 1) The Lord reigneth; let the people tremble. R. Samuel b. Nachmeni said (Ib. 93, 1) The Lord reigneth; He is clothed in majesty. R. Isaac Naphcha said: Sing, O ark, in beauty shining; Thou adorned with chains of gold — ever close the Word enshrining — glittering with gems untold." R. Ashi taught the saying of R. Isaac Naphcha in connection with this (Num. 10, 55) And it came to pass, when the ark set forward that Moses said, etc. And what did Israel say? Whereupon R. Isaac said: "Sing, O ark, etc."

Similarly, it is written concerning Jehoshaphat: And when he had taken counsel with the people, he appointed them that should sing unto the Lord, and praise in the beauty of holiness, as they went out before the army, and say: “Give thanks unto the Lord, for His mercy endureth forever” (II Chron. 20:21). What is the difference between this song of praise and others found in the Torah? In all the other songs, For He is good is added, but in this instance For He is good is omitted, since there can be no rejoicing before Him on High over the destruction of the wicked. And since there could be no rejoicing before Him over the destruction of the wicked, surely there could be no joy at the destruction of the righteous, a single one of whom is equal to all the world in His sight. Hence it is said: But the righteous is an everlasting foundation (Prov. 10:25). The ninth song is the Song of Songs of Solomon. The tenth song is the song of the future: A psalm, O sing unto the Lord a new song; for He hath done marvelous things (Ps. 98:1).
