Chapter 13

David.

1st, David asks how long until God turns back to him.  How long will God hide his face?

This is very sad.  David is feeling separated from God, and indeed God has turned away from him, because of his sins of adultery and murder.  For his abuse of the power God gave to him.  It is the same for us.  When we intentionally, knowingly sin, replacing God's wisdom for our lives with our own desires of the flesh, this separation is what happens.  God leaves us to deal with what passes for cause and effect in this world, and that is a very lonely way to live.

2nd, Asking God to consider, or more likely to reconsider.

3rd, Yet David will keep trusting, because despite all, God's blessings still outweigh the current woes.
