Communication between the writer and God could not be better: he calls, God answers.
Psalm 139
Props to God for being ever-present and all-knowing. He was there when you were created, and he'll be there when you die. It's actually an important assertion for the time—it means God isn't just a storm god anymore.
Psalm 140
The enemies of God are back, and the writer can only hope he's on the right side.
Psalm 141
The author hopes that his friends will keep him and his faith in line.
Psalm 142
God serves as the writer's refuge. He's pretty cozy.
Psalm 143
Time for a Q&A with God: is anyone truly innocent? Either way, the writer wants God to lead him into righteousness.
Psalm 144
God's back—but now he's a battle trainer. Here's the thing: in the ancient world, victory in battle meant peace for a while, so God needed to show his face there, too.
Psalm 145
The author expresses his desire for these stories and laws to be transmitted through the generations, and expresses his awe at God's power.
Psalm 146
We feel like we've heard this one before: God performs miracles, and the writer warns the audience not to trust mortals more than God.
Psalm 147
We're getting toward the end, and God now names the stars. Remind you of Genesis, when Adam names the creatures of the earth? It should. God and man both have their respective zones, but God is creator and master of all. Natch.
Psalm 148
Another call to action: the writer wants all creatures to praise God.
