Psalm 88:1

A song. A psalm of the sons of Korah. For the choir director. To the tune of "Mahalath Leannoth." A maskil of Heman the Ezrahite.
LORD, you are the God who saves me.
Day and night I cry out to you.

Psalm 88:1, Readable English Bible (READ)

Note: The meaning of "Mahalath Leannoth" and "maskil" is not certain; they are probably music or song terms.
