47. We learned that shirah (Eng. 'poem') draws blessings from above downward, until there are blessings throughout the worlds. Rabbi Elazar said, Yisrael will recite a poem from below upward and from above downward, and to bind the bond of Faith, as it is written, "Then Yisrael sang (lit. 'will sing') this song (Heb. shirah)" (Bemidbar 21:17). It speaks in the future tense rather than in the past. And so is everything the same way, IN THE FUTURE TENSE. "This shirah" is from below upward, BECAUSE SHIRAH IS IN MALCHUT THAT SINGS UPWARDS TO ZEIR ANPIN, "Spring up, O well, sing to it" (Ibid.). "Spring up, O well," namely, THEY SPOKE TO MALCHUT CALLED A WELL, rise to your place to join your husband ZEIR ANPIN. This is from below upward, RAISING MALCHUT TO ZEIR ANPIN.

48. Afterwards THEY DRAW from above downward, "the well that the princes dug out" (Ibid. 18). THE WELL IS MALCHUT; "the princes dug out," as Aba and Ima begot her, BECAUSE ABA AND IMA FORMED MALCHUT ACCORDING TO THE SECRET OF, "THE SIDE, WHICH HASHEM ELOHIM HAD TAKEN" (BERESHEET 2:22); "the nobles of the people delved" (Bemidbar 21:18) are the patriarchs, NAMELY CHESED, GVURAH AND TIFERET OF ZEIR ANPIN called the nobles of the people. They delved it, NAMELY THEY DELVED A PLACE for the King to unite with her with blessings. How? Through union. "With the scepter" (Ibid.) refers to Yesod, "with their staves" (Ibid.) refers to Netzach and Hod. UP TO HERE is from above downward. "From the wilderness" (Ibid. 19), WHICH IS MALCHUT CALLED SPEECH, "to Matanah" (Ibid.) IT RISES TO YESOD CALLED MATANAH. "And from Matanah it rises to Nahaliel," WHICH IS TIFERET, "and from Nahaliel to Bamot" (Ibid.), WHICH IS ABA AND IMA. This is the complete bond, the bond of Faith, the bond that incorporates sustenance for everything.

49. Rabbi Yosi said, Yisrael will recite a complete poem, a poem including all other songs. This is the meaning of, "O give thanks to Hashem; call upon His name. Make known His deeds among the people" (Tehilim 105:1). Of that time it is written, "on that day Hashem shall be one, and His Name One" (Zacharia 14:9), and, "Then was our mouth filled with laughter, and our tongue with singing. Then they said among the nations, Hashem has done great things for them" (Tehilim 126:2).
