Rabbi Aryeh Kaplan explains that the key to establishing a palpable closeness to G-d when we say the Shemoneh Esrai, are the words Melekh (King), Ozer (Helper), uMoshia (Rescuer), uMogen (Shield) in the first brocha. We start off addressing G-d as a majestic but somewhat distant King. A Helper is more available and closer than a King, like a friend who we know we can call on. A Rescuer is closer than a Helper, because he is right there to save us when we need help. A Shield is closer than a Rescuer because he is surrounding us, protecting us from harm. If we say these four words slowly (4+ seconds per word), focusing on the different perceptions of closeness, we can sense Hashem’s protection.
This four word progression is also applicable to the Yomim Noraim. On Rosh Hoshana we focus on Hashem as King. In the ten days of Teshuva, we call out more in Selichos to Hashem, our Rescuer, because He is more available in this period. On Yom Kippur, we pray and confess to Hashem, our Saviour, as He saves us from the consequences of our sins. On Succos, we focus on Hashem, our Shield, through the mitzvos of the Sukkah and the feelings of protection that it generates.
The idea of the progression from King, to Helper, to Rescuer, to Shield, might help explain a question regarding brochos. Every standalone or sequence-beginning brocha must contain Hashem’s name and the word Melekh. However, the beginning of Shomeneh Esrai is missing the Melekh. Tosfos gives the most quoted answer: the first Brocha mentions Avrahom, who was the first one who made Hashem King over himself. The question still remains: why not just put the word Melekh, like we find in every other brocha?
Perhaps we can say that the word Melekh by itself represents a distant King. However in Shomeneh Esrai we are talking directly to Hashem, To help us create that conversational closeness, the Men of the Great Assembly, put the word Melekh at the end of the brocha in the progression leading to Magen. This is the relationship Avrahom personified, and that is the relationship we are pursuing in the first brocha and in the entire Shomoneh Esrai.
May we all merit to make the progression from Melekh to Magen in these upcoming Yomim Noraim, and in every tefillah that we daven.
