Revelation 19:9

Then the angel said to me, "Write: 'Blessed are those who are invited to the wedding supper of the Lamb!'" And he added, "These are the true words of God."

Then the angel said to me
Revelation 17:1 One of the seven angels who had the seven bowls came and said to me, "Come, I will show you the punishment of the great prostitute, who sits on many waters."
Revelation 19:10 At this I fell at his feet to worship him. But he said to me, "Do not do it! I am a fellow servant with you and with your brothers who hold to the testimony of Jesus. Worship God! For the testimony of Jesus is the spirit of prophecy."

Write
