Revelation 15:1-4

Then I witnessed another great and astonishing sign in heaven: seven angels bringing the last seven plagues, for with them the wrath of God is finished. Then I saw what looked like a vast sea of glass blended with fiery flames. Standing beside the sea were those who continually conquer the wild beast, his image and the number of his name. They each held the harps of God and they were singing the song of Moses, God’s servant, and the song of the Lamb: “Mighty and marvelous are your miracles, Lord YAHWEH, God Almighty! Righteous and true are your ways, O Sovereign King of the ages! Who will not reverence you with awe, O Lord, and bring glory to your name? For you alone are holy, and all nations will come and bow in worship before you, as your blessings have revealed.”
