Psalm 39 – In this psalm the suffering person expresses bewilderment to God for his suffering.  In many ways it is a lament on how fleeting and sad life is.    

1-3 – The singer is trying to be quiet in his suffering and not to say anything disparaging about God in front of the wicked, but finally he speaks.  What follows next is worship, the only appropriate thing to say before God.

4-6 – The singer prays to know how fleeting is his life so that he may not engage in the turmoil of life trying to heap up wealth.

7-13 – The singer confesses his sin, which is perhaps partly responsible for his suffering.  The singer asks the LORD to deliver him from all of his transgressions and to take away God’s discipline for sin, and then he waits upon the LORD.  The final thought is a confession that the singer is just a sojourner, a guest in this present life, as are all men.
