'Singing' in the Bible

They were singing a new song: "You are worthy to take the scroll and to open its seals because you were killed, and at the cost of your own blood you have purchased for God persons from every tribe, language, people, and nation.

all of whom were singing in a loud voice: "Worthy is the lamb who was killed to receive power and wealth and wisdom and might and honor and glory and praise!"

Then I heard every creature -- in heaven, on earth, under the earth, in the sea, and all that is in them -- singing: "To the one seated on the throne and to the Lamb be praise, honor, glory, and ruling power forever and ever!"

and they were singing a new song before the throne and before the four living creatures and the elders. No one was able to learn the song except the one hundred and forty-four thousand who had been redeemed from the earth.
