'Singing' in the Bible
After singing a hymn, they went out to the Mount of Olives.
About midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them,
and in loud voices they were singing, "It is fitting that the Lamb which has been offered in sacrifice should receive all power and riches and wisdom and might and honor and glory and blessing."
And they were singing what seemed to be a new song, in front of the throne and in the presence of the four living creatures and the Elders; and no one was able to learn that song except the 144,000 people who had been redeemed out of the world.
And they were singing the song of Moses, God's servant, and the song of the Lamb. Their words were, "Great and wonderful are Thy works, O Lord God, the Ruler of all. Righteous and true are Thy ways, O King of the nations.
