'Love song' in the Bible

Arise! Deliver us! Redeem us according to your gracious love! To the Director: An instruction by the Sons of Korah. A love song to the tune of "Lilies".

For the music director; according to the tune of "Lilies;" by the Korahites, a well-written poem, a love song. My heart is stirred by a beautiful song. I say, "I have composed this special song for the king; my tongue is as skilled as the stylus of an experienced scribe."
