Revelation 19:1: "1 After this I heard what seemed to be the loud voice of a great multitude in heaven, crying out, 'Hallelujah! Salvation and glory and power belong to our God'"
Psalm 145:15-16: "15 The eyes of all look to you, and you give them their food in due season. 16 You open your hand; you satisfy the desire of every living thing."
Revelation 7:9-17: "9 After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, 10 and crying out with a loud voice, 'Salvation belongs to our God who sits on the throne, and to the Lamb!' 11 And all the angels were standing around the throne and around the elders and the four living creatures, and they fell on their faces before the throne and worshiped God, 12 saying, 'Amen! Blessing and glory and wisdom and thanksgiving and honor and power and might be to our God forever and ever! Amen.'
"13 Then one of the elders addressed me, saying, 'Who are these, clothed in white robes, and from where have they come?' 14 I said to him, 'Sir, you know.' And he said to me, 'These are the ones coming out of the great tribulation. They have washed their robes and made them white in the blood of the Lamb.
"15 'Therefore they are before the throne of God, and serve him day and night in his temple; and he who sits on the throne will shelter them with his presence. 16 They shall hunger no more, neither thirst anymore; the sun shall not strike them, nor any scorching heat. 17 For the Lamb in the midst of the throne will be their shepherd, and he will guide them to springs of living water, and God will wipe away every tear from their eyes.'"
Titus 3:4-7: "4 But when the goodness and loving kindness of God our Savior appeared, 5 he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit, 6 whom he poured out on us richly through Jesus Christ our Savior, 7 so that being justified by his grace we might become heirs according to the hope of eternal life."

Revelation 19:1 seems to appear in the recurring line "Alleluia! Let praises ring!" at the beginning of each verse.
The passage from Psalm 145:15-16 seems to be the basis for the line "Whose hand sustains creation" in the first verse and possibly also the line "There is manna" in the third verse.
The passage from Revelation 7 appears throughout the hymn but especially in the first verse, the lines "He bought His Church with His own blood, / He cleansed her in that blessed flood" in the second verse, and "With angel hosts let us adore / And sing His praises evermore" in the fourth verse.
The passage from Titus 3 is combined with Revelation 7:14 in the lines "He bought His Church with His own blood, / He cleansed her in that blessed flood" in the second verse and is also alluded to in the lines "Unto the Holy Ghost we sing / For our regeneration" in the third verse.

The lines "Holy, holy, / God is holy" in the first and fourth verses may refer to the "Holy, holy, holy" in Isaiah 6:3 or Revelation 4:8.
The title "the Lamb of God" in the second verse comes from John 1:29, 36.
The line "Made us His chosen nation" in the third verse may refer to 1 Peter 2:9: "But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light."
