Avinu Malkeinu

Avinu Malkeinu (Hebrew: אָבִינוּ מַלְכֵּנוּ; "Our Father, Our King") is a Jewish prayer recited during Jewish services during the Ten Days of Repentance, from Rosh Hashanah through Yom Kippur inclusive. Since the 17th century, most Eastern Ashkenazi Jewish communities recite it on all ta'aniyot (תַּעֲנִיּוֹת, 'fast days'), as well; in the Sephardic and Western Ashkenazic traditions (as well as a very few Eastern Ashkenazic communities), it is recited only during the Ten Days of Repentance. Joseph H. Hertz (died 1946), Chief Rabbi of the United Hebrew Congregations of the Commonwealth, described it as "the oldest and most moving of all the litanies of the Jewish Year". It makes use of two sobriquets for God that appear separately in the Hebrew Bible: "Our Father" (Isaiah 63:16) and "Our King" (Isaiah 33:22).
