שְׁמַע־יְהוָ֥ה וְחָנֵּ֑נִי יְ֝הוָה הֱֽיֵה־עֹזֵ֥ר לִֽי׃
הער, גאָט, און לײַטזעליק מיך, גאָט, זײַ מיר אַ העלפֿער. ”
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.
