'Hymns' in the Bible

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

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

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