"an ode, song," is always used in the NT (as in the Sept.), in praise of God or Christ; in Ephesians 5:19; Colossians 3:16 the adjective "spiritual" is added, because the word in itself is generic and might be used of songs anything but spiritual; in Revelation 5:9; 14:3 (1st part) the descriptive word is "new" (kainos, "new," in reference to character and form: see NEW), a "song," the significance of which was confined to those mentioned (ver. 3, and 2nd part); in Revelation 15:3 (twice), "the song of Moses ... and the song of the Lamb," the former as celebrating the deliverance of God's people by His power, the latter as celebrating redemption by atoning sacrifice.
