'Marvelous' in the Bible

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].

And they sang the song of Moses, the bond-servant of God, and the song of the Lamb, saying,“Great 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!
