'Hymns' in the Bible

About midnight Paul and Silas were praying and singing hymns to God, and the rest of the prisoners were listening to them.

speaking to one another in psalms, hymns, and spiritual songs, singing and making music in your hearts to the Lord,

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