'Hymns' in the Bible

But about midnight Paul and Silas were praying and singing hymns unto God, and the prisoners were listening to them;

speaking one to another in psalms and hymns and spiritual songs, singing and making melody with your heart to the Lord;

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