Psalm 40

Psalm 40 is the 40th psalm from the Book of Psalms.

Matthew Henry calls the psalm a "Confidence for deliverance. (1-5) Christ's work of redemption. (6-10) and a Prayer for mercy and grace. (11-17)" While some see in it the prophetic of Jesus or messiah generally.

John Westley saw it as a prayer of salvation.

The first part of the Psalm (verses 1-11) is one in the series of psalms of thanksgiving of an individual.

Verses 13-18 set originally possibly an independent Psalm context, because it is virtually identical to Psalm 70. This part belongs more in the group of psalms of lament.

The Psalm was used in the song 40, also known as "How Long", the final track from U2's 1983 album, War.

A song by The Mountain Goats titled "Psalm 40:2" appears on their 2009 album The Life of the World to Come, inspired by the same verse.
