Hallelujah
Hallelujah (/ˌhæləˈluːjə/ HAL-ə-LOO-yə; Biblical Hebrew: הַלְלוּ־יָהּ, romanized: hallū-Yāh, Modern Hebrew: הַלְּלוּ־יָהּ, romanized: halləlū-Yah, lit.'praise Yah') is an interjection from the Hebrew language, used as an expression of gratitude to God.[1][2]
The term is used 24 times in the Hebrew Bible (in the book of Psalms), twice in deuterocanonical books, and four times in the Christian Book of Revelation.[3]
The phrase is used in Judaism as part of the Hallel prayers, and in Christian prayer,[3] where since the earliest times[4] it is used in various ways in liturgies,[5] especially those of the Catholic Church, the Lutheran Churches and the Eastern Orthodox Church,[6][7] the three of which use the Latin form alleluia which is based on the alternative Greek transliteration.[1]
