הָפַ֣כְתָּ מִסְפְּדִי֮ לְמָח֪וֹל לִ֥י פִּתַּ֥חְתָּ שַׂקִּ֑י וַֽתְּאַזְּרֵ֥נִי שִׂמְחָֽה׃
你把我的哀哭變為跳舞，脫去我的麻衣，給我束上喜樂。
Siddur Ashkenaz
Psalm 30, once used to inaugurate the Holy Temple, is used today to inaugurate our daily prayers, for the synagogue is a “Holy Temple in miniature” and our prayers take the place of the sacrifices. It is both a prayer for success and a declaration of thanksgiving.
