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.
Perek Shirah
And the Mouse says, “I shall exalt you, YHVH, for you have impoverished me, and you have not let my enemies rejoice over me.”
