'Singing' in the Bible

And at midnight Paul and Silas, in praying, were praising God with singing, and the prisoners listened to them.

speaking to yourselves in psalms and hymns and spiritual songs, singing and chanting with your heart to the Lord;

Let the word of the Christ dwell in you richly, in all wisdom teaching and admonishing one another, in psalms, hymns, spiritual songs, singing with grace in your hearts to God.
