He recites before them 24 benedictions, eighteen of the daily prayers and additional six. These are they, Zikhronot and Shofarot⁷⁴The two additional benedictions in the musaf prayer of New Year’s Day; each one accompanied by the blowing of the shofar. The text of each addition is followed by an invocation and a doxology as spelled out in Mishnaiot 4–10.. To the Eternal in my straights⁷⁵Ps. 120.. I lifted my eyes to the Mountains⁷⁶Ps. 121.. From the depths I called on You, Eternal⁷⁷Ps. 130.. Prayer of the poor who is fainting⁷⁸Ps. 102.
