Tze’enah U’Re’enah
This is a niggun d'veikus that the Alter Rebbe would sing. There is another part to the niggun that was not verified, so it is not recorded in Sefer Haniggunim.
On Shavuos 5701 (1941) the Frierdiker Rebbe described how, in the year 5637, a large crowd of Chassidim came to the Alter Rebbe for Shavuos. There wasn’t enough room in the usual davening place, so they built a temporary, “shed-like” shul in the courtyard. As the Alter Rebbe left his house to go to the courtyard shul he said - in his typical, holy singsong - “’Tze’enah ure’enah’ (‘Go and out and see’, quoted from Shir Hashirim): ’Tze’enah,’ when one leaves the self, the ‘I’, on all levels, then ’u’re’enah’, one sees Elokus (Divinity).”
lyrics:
צְאֶינָה וּרְאֶינָה בְּנוֹת צִיּוֹן בַּמֶּלֶךְ שְׁלֹמֹה בָּעֲטָרָה שֶׁעִטְּרָה לּוֹ אִמּוֹ בְּיוֹם חֲתֻנָּתוֹ וּבְיוֹם שִׂמְחַת לִבּוֹ
Go out, daughters of Tzion, and gaze upon King Shlomo, upon the crown with which his mother crowned him on his wedding day and on the day of the joy of his heart.
