יְֽהוָ֗ה בִּרְצוֹנְךָ֮ הֶעֱמַ֪דְתָּה לְֽהַרְרִ֫י עֹ֥ז הִסְתַּ֥רְתָּ פָנֶ֗יךָ הָיִ֥יתִי נִבְהָֽל׃
永恆者啊，你曾施恩，使我的山堅固穩立；你一掩面，我就驚惶失措。
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.
