Psalm 109:1 - Psalm 134:3
David is very graphic in his prayers. He really wants his enemies to suffer for what they have done to David and/or the Lord. David wants a wicked man to be as his enemy's god and Satan to be at his right hand.
"Set thou a wicked man over him: and let Satan stand at his right hand." Psalm 109:6
Wow, I want to stay on David's good side.
