Psalms 3 & 4 are anxious. They speak of a Lord Deliverer, but suggest a current state of unease. How long will people turn my glory (faith in YHWH) into shame (foolishness? naïveté?) It is a familiar feeling
Psalm 12 is similar but more of a collective angst. No one believes anymore, type of thing. They elected Donald Trump. The psalmist puts into the voice of God, “Because the poor are plundered and the needy groan, I will now arise.” Again, indicated that some rising is called for. The angst in Psalm 13 is more personal. “How long must I wrestle with my thoughts.”
Psalm 28 talks about personal experience with God, but then celebrates God’s relationship with God’s people.
Psalm 55 takes a different tone, IMHO. It starts off, “Listen to my prayer, God.” Feeling more like a command than a request. Then it lists how God always sides with the righteous, then invites God to kill the psalmist’s enemies.
Each of these are emotional. Even the last one seems more about feelings than theology. I try to use them as a guide into the meditations of ancient people and as a way to find some communion with their innermost thoughts.
