or HALLELU-JAH, הללו־יה, _praise the Lord_; or, _praise to the Lord_: compounded of הללו, _praise ye_, and יה, _the Lord_. This word occurs at the beginning, or at the end, of many Psalms. Alleluia was sung on solemn days of rejoicing: “And all her streets shall sing Alleluia,” says Tobit, speaking of the rebuilding of Jerusalem, Tob. xiii, 18. St. John, in the Revelation, xix, 1, 3, 4, 6, says, “I heard a great voice of much people in heaven, who cried, Alleluia; and the four living creatures fell down, and worshipped God, saying, Alleluia.” This expression of joy and praise was transferred from the synagogue to the church. At the funeral of Fabiola, “several psalms were sung with loud alleluias,” says Jerom, in _Epitaphio Paulæ_, “The monks of Palestine were awaked at their midnight watchings, with the singing of alleluias.” It is still occasionally used in devotional psalmody.
