Title: Psalm 6
Content:  Psalm 6 is the sixth psalm from the Book of Psalms. The Psalm gives its author as King David. David's supposed intention in writing the psalm was that it would serve as a prayer for anyone suffering from sickness or distress or for the state of the Kingdom of Israel while suffering through oppression. The Geneva Bible (1599) gives the following summary:"When David by his sins had provoked God’s wrath, and now felt not only his hand against him, but also conceived the horrors of death everlasting, he desireth forgiveness. 6 Bewailing that if God took him away in his indignation, he should lack occasion to praise him as he was wont to do while he was among men. 9 Then suddenly feeling God’s mercy, he sharply rebuketh his enemies which rejoiced in his affliction." The psalm is the first of the seven Penitential Psalms, as identified by Cassiodorus in a commentary of the 6th century AD. Many translations have been made of these psalms, and musical settings have been made by many composers.
