Each morning, after the recitation of Hodu, we recite the 30 th chapter of Tehillim, which begins "Mizmor Shir Hanukat Ha'bayit Le'David." Sephardic practice is to omit this introductory verse, and to begin with the next verse – "Aromimcha Hashem Ki Dilitani…" The Arizal (Rav Yishak Luria, Safed, 1534-1572) taught about the importance of reciting this chapter each morning as part of the prayer service, though it is found already in earlier Siddurim, from the late 15 th century. After this recitation, we arrive at a particularly important point of the morning service – the declaration of "Hashem Melech, Hashem Malach, Hashem Yimloch Le'olam Va'ed" ("Hashem is King, Hashem has reigned, Hashem will reign for all eternity"). This declaration appears nowhere in Tanach, but is a composite of phrases from three different verses. The phrase "Hashem Melech" is taken from a verse in Tehillim (10:16 ) – "Hashem Melech Olam Va'ed, Abedu Goyim Me'arso." The source of the phrase "Hashem Malach" is a later chapter in Tehillim (97), which begins, "Hashem Malach, Ge'ut Labesh." Finally, "Hashem Yimloch Le'olam Va'ed" appears at the conclusion of Az Yashir, the song of praise which Beneh Yisrael sang after the miracle of the splitting of the sea (Shemot 15:18 ). The Shiboleh Ha'leket (Rav Sidkiya Ben Abraham Ha'rofeh, Rome, 13 th century) cites Rabbenu Binyamin as explaining the custom to make this pronouncement in the morning based on the Midrash's description of the angels' daily praise of G-d. Each morning, the Midrash states, one angel stands in the center of the heavens and declares, "Hashem Melech…" whereupon all the other angels repeat this pronouncement. In commemoration, here in our world, too, the Hazzan makes this declaration in the synagogue, followed by the rest of the congregation. We stand for this recitation because the angels are always in a standing position. Some communities had the practice of proclaiming "Hashem Melech" only on Shabbat, but already the Bet Yosef (Maran Rav Yosef Karo, author of the Shulhan Aruch) observes the custom in his time to recite "Hashem Melech" each morning. This is, indeed, the common custom today. The proclamation of "Hashem Melech" is followed by the recitation of the 67 th chapter of Tehillim – "La'menase'ah Bi'nginot Mizmor Shir." This is an especially significant chapter of Tehillim, and the Arizal taught that this recitation has the power to protect a person throughout the day and bring great prosperity. It is customary to write this chapter of Tehillim in the shape of a Menorah and to hang it in the synagogue. The Rokeah (Rav Eliezer of Worms, Germany, c. 1176-1238) taught that a synagogue which has this chapter on the Aron is guaranteed protection.
