signifies "Praise ye Jah." It occurs as a short doxology in the Psalms, usually at the beginning, e.g., Psalm 111; 112 , or the end, e.g., Psalm 104; 105 , or both, e.g., Psalm 106; 135 (where it is also used in ver. 3), Psalm 146; 147; 148; 149; 150 . In the NT it is found in Revelation 19:1,3,4,6 , as the keynote in the song of the great multitude in heaven. "Alleluia," without the initial "H," is a misspelling.
