'Song' in the Bible

And they sang a new song [of glorious redemption], saying,“Worthy and deserving are You to take the scroll and to break its seals; for You were slain (sacrificed), and with Your blood You purchased people for God from every tribe and language and people and nation.

And they sang a new song before the throne [of God] and before the four living creatures and the elders; and no one could learn the song except the hundred and forty-four thousand who had been purchased (ransomed, redeemed) from the earth.

And they sang the song of Moses, the bond-servant of God, and the song of the Lamb, saying,“Great and wonderful and awe-inspiring are Your works [in judgment],O Lord God, the Almighty [the Omnipotent, the Ruler of all];Righteous and true are Your ways,O King of the nations!
