Here, God provides strength not through military might, but through his name alone. Intense.
This psalm is a monarchy endorsement if ever there was one. Read and be convinced.
This depressed dude is having what can only be described as a terrible, horrible, no good, very bad day; his heart has turned to wax, and he's surrounded by wild beasts. Yikes. He's half furious that God let things get this far and half praiseworthy of God's great ways. He'll figure it out, we hope.
