'Hymns' in the Bible

He appointed some of the Levites to serve before the ark of the Lord, to offer prayers, songs of thanks, and hymns to the Lord God of Israel.

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.
