Psalms 40:3 NLT
He has given me a new song to sing, a hymn of praise to our God.
Many will see what he has done and be amazed.
They will put their trust in the LORD.

Revelation 5:6-10
Then I saw a Lamb, looking as if it had been slain, standing at the centre of the throne, encircled by the four living creatures and the elders. The Lamb had seven horns and seven eyes, which are the seven spirits of God sent out into all the earth. He went and took the scroll from the right hand of him who sat on the throne. And when he had taken it, the four living creatures and the twenty-four elders fell down before the Lamb. Each one had a harp and they were holding golden bowls full of incense, which are the prayers of God’s people. 
And they sang a new song, saying:
You are worthy to take the scroll
    and to open its seals,
    because you were slain,
    and with your blood you purchased for God
    persons from every tribe and language and people and nation.
You have made them to be a kingdom and priests to serve our God,
    and they will reign on the earth.
