ק֤וֹל ׀ רִנָּ֬ה וִֽישׁוּעָ֗ה בְּאָהֳלֵ֥י צַדִּיקִ֑ים יְמִ֥ין יְ֝הוָה עֹ֣שָׂה חָֽיִל׃
Le son des chants de joie et de salut [retentit] dans les tentes des justes: la droite de l’Éternel procure la victoire.
Shulchan Arukh, Orach Chayim
One should not say liturgical poems nor a "krovetz" (meaning "krovot l'Yotzeir" [close to the blessing of Yotzeir Or], and some say it is an acronym for "Kol Rina Vi-shua B'ohalei Tzadikim" [Psalms 118:15]) during the prayer [i.e. Amidah]. Gloss: And there are those who permit [them], since they are [considered] needs of the public (the Rosh; Tosefot; the Ri; and the Ran at the beginning of the last chapter of Tractate Rosh Hashana; and Hagahot Maimoni, chapter 10; and the Tur), and such it is practiced in all places to say them.
