'Songs' in the Bible

But about the middle of the night, Paul and Silas were making prayers and songs to God in the hearing of the prisoners;

Speaking to yourselves in psalms and 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 in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
