("Mighty in Kingship"). Alphabetical acrostic hymn, first mentioned in the 13th century, which Ashkenazim chant toward the end of their Passover
Seder ritual. Each of the eight stanzas mentions two Divine attributes and one class of angelic praise; the hymn, also known from its refrain as
Ki Lo Na'eh ("For to Him praise is becoming"), was inspired by a Midrash (Gen. R. 6:2). In the medieval Franco-German rite,
Addir bi-Melukhah may have been recited on the first
Seder night and
Addir Hu on the second; however, both have long been sung on the two nights. The composer's identity is uncertain, but he probably lived in France or Germany.
