Each morning before Baruch She'amar, the congregation stands and the Hazan declares, "Hashem Melech, Hashem Malach, Hashem Yimloch Le'olam Va'ed" – "Hashem is King, Hashem was King, Hashem will be King for all eternity." The congregation then repeats this proclamation after the Hazan. Our custom is to make this proclamation twice. There is an opinion that a Minyan is required for pronouncing "Hashem Melech," but the accepted view is that this may be said even without a Minyan, and so if ten men have yet to arrive by this point, "Hashem Melech" may nevertheless be recited. Some communities have the practice that a child leads the congregation in reciting "Hashem Melech." It would seem, however, that it is more proper to choose someone who is at least Bar-Misva age to lead this proclamation. The Ben Ish Hai (Rav Yosef Haim of Baghdad, 1833-1909) brings a custom to lift one's feet when reciting "Hashem Melech," like we do when reciting "Kadosh, Kadosh, Kadosh." This symbolizes the "elevation" that we experience through this recitation, as we make our way toward the higher realms until we reach the highest level in the heavens so we can recite the Amida directly in Hashem's presence. One who follows this custom must ensure to do so in a discreet, unassuming manner, and not in a way that draws attention to himself. The Arizal (Rav Yishak Luria, Safed, 1534-1572) taught that the pronouncement of "Hashem Melech" is associated with our quest to neutralize the 280 "Kelipot," or negative energies, that threaten us. These 280 forces are alluded to in the names of the five letters of the Hebrew alphabet that are changed when they appear at the end of a word: Mem, Nun, Sadi, Peh, Kaf (represented by the acrostic "Mansapach"). The combined numerical value of these letters is 280. When we succeed in "subjugating" these 280 forces, the Arizal taught, Mashiah will come. In the proclamation of "Hashem Melech," the words "Melech" and "Malach" both have the Gematria of 90, and the word "Yimloch" equals 100 – for a total of 280, thus alluding to the "Kelipot." The Name of "Havaya" is mentioned three times in this proclamation ("Hashem Melech, Hashem Malach, Hashem Yimloch"), and in Gematria it equals 26, for a total of 78 (26 * 3). Adding this to 280, we arrive at a total of 358 – the Gematria of "Mashiah" (40+300+10+8). This daily proclamation, then, is a crucial part of our effort to overcome the harmful spiritual forces in the world so that we will become worthy of the arrival of Mashiah.
