In the New Testament, ALLELUIAH, Praise ye Jehovah. This word occurs at the beginning and at the end of many psalms. It was also sung on solemn days of rejoicing, as an expression of joy and praise, and as such it has been adopted in the Christian church, and is still used in devotional psalmody, Revelation 19:1,3,4,6 .
