Psalm 25 is a lament psalm.
David makes multiple petitions. There are multiple mentions of enemies and his own sin, which is usually what the lament is made of. There’s an invocation. There are expressions of confidence. There are times of praise.
But because these elements are split up and oftentimes repeated - some have thought that Psalm 25 is not a lament psalm.
But I actually think that because it has all of these components of a typical lament psalm, it’s best to interpret this psalm as a lament – rather than as, say, a meditative psalm or something else.
So, David is working through some problem in his life with God’s help. That’s what is happening in a lament psalm.
