Revelation 15:1-3

Then I saw another sign in heaven, great and wonderful [a warning of terrifying and horrible events]: seven angels who had seven plagues (afflictions, calamities), which are the last, because with them the wrath of God is finished [that is, it is completely expressed and reaches its zenith]. [Lev 26:21] Then I saw something like a sea or large expanse of glass mixed with fire, and those who were victorious over the beast and over his image and over the number corresponding to his name were standing on the sea or large expanse of glass, holding harps of God [worshiping Him]. [Rev 4:6; 7:9-17] And they sang the song of Moses, the bond-servant of God, and the song of the Lamb, saying, “ G reat and wonderful and awe-inspiring are Your works [in judgment], O Lord God, the Almighty [the Omnipotent, the Ruler of all]; Righteous and true are Your ways, O King of the nations! [Ex 15:1-8; Ps 145:17]
