Sing joyful songs to the Lord!
    Praise the mighty rock
    where we are safe.
Come to worship him
with thankful hearts
    and songs of praise.
The Lord is the greatest God,
    king over all other gods.
Psalm 95:1-4

Then I looked and saw a Lamb standing in the center of the throne
that was surrounded by the four living creatures and the elders.
The Lamb looked as if it had once been killed.
The Lamb went over and took the scroll
from the right hand of the one who sat on the throne.
After he had taken it, the four living creatures and
the twenty-four elders knelt down before him.
Then they sang a new song:
You are worthy
    to receive the scroll
and open its seals,
    because you were killed.
And with your own blood
    you bought for God
people from every tribe,
    language, nation, and race.
Revelation 5:6-10
