Revelation 15

The Song of Moses and the lamb. It is the deliverance song that the saints will sing from the curse of sin. It is the reality (i.e. the anti-type) to the story where the Israelites sing after they have been delivered out of Egypt from Pharaoh's hands (Exodus 15:1-18). This story - true story - I believe is a type (symbol) of what will happen when all of the righteous are delivered out of the spiritual Egypt/Babylon of this world - at the end of the world: from the Pharaoh of this world - which is Satan himself and his ugly demonic hordes henchmen.
