Revelation 5:9-10

 And they sang a new song, saying:

“You are worthy to take the scroll,

And to open its seals;

For You were slain,

And have redeemed us to God by Your blood

Out of every tribe and tongue and people and nation,

And have made us kings and priests to our God;

And we shall reign on the earth.”

 

Psalm 40:3  He has put a new song in my mouth – praise to our God; many will see it and fear, and will trust in the LORD.

John 1:29  The next day John saw Jesus coming toward him, and said, “Behold!  The Lamb of God who takes away the sin of the world!”
