Revelation 15:1-2

New Revised Standard Version Catholic Edition

The Angels with the Seven Last Plagues

15 Then I saw another portent in heaven, great and amazing: seven angels with seven plagues, which are the last, for with them the wrath of God is ended.

² And I saw what appeared to be a sea of glass mixed with fire, and those who had conquered the beast and its image and the number of its name, standing beside the sea of glass with harps of God in their hands.
