'Might in Kingship'), also known as Ki Lo Naʾeh (Hebrew: כִּי לוֹ נָאֶה, romanized: Kī Lō Nāʾē, lit.
'For Him it is Fitting'), is a Hebrew Jewish piyyut (liturgical poem), usually recited near the end of the Passover Seder.
Adir Bimlukha is written as a hymn of praise to God, and is based on numerous Biblical verses.
[2] The earliest sources for Adir Bimlukha are 13th century manuscripts from Germany, which is the milieu in which this piyyut was likely composed.
[3][1] Most Jewish communities sing Adir Bimlukha on both nights of Passover shortly before drinking the fourth cup of wine.
