וַ֭אֲנִי אָמַ֣רְתִּי בְשַׁלְוִ֑י בַּל־אֶמּ֥וֹט לְעוֹלָֽם׃
至於我，我在安穩的時候曾說：「我永遠不會動搖。」
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.
