For the director of music. To the tune of "Lilies." Of the Sons of Korah. A maskil. A wedding song. My heart is stirred by a noble theme as I recite my verses for the king; my tongue is the pen of a skillful writer.
NIV
To the Chief Musician; [set to the tune of] "Lilies" [probably a popular air. A Psalm] of the sons of Korah. A skillful song, or a didactic or reflective poem. A song of love. MY HEART overflows with a goodly theme; I address my psalm to a King. My tongue is like the pen of a ready writer.
AMP
My heart is inditing a good matter: I speak of the things which I have made touching the king: my tongue is the pen of a ready writer.
