New Defender's Study Bible Notes
19:1 Alleluia. The great cry, “Alleluia,” sounds out four times from the great assembly in heaven (Revelation 19:1, 3, 4, 6), and these are the only occurrences of the word in the New Testament. Meaning, “Praise the Lord!” it is the same as “Hallelujah,” and occurs in the Hebrew in the first and last verses of each of the last five psalms of the book of Psalms. These final “Hallelujah Psalms” thus may well represent the praise songs of all the redeemed as they gather in preparation for the great marriage supper of the Lamb (Revelation 19:9).
