Oh, please, don’t kill me! I’m up to my neck in hot water! I’m sinking in quicksand! I’m in over my head! There was an earthquake! A terrible flood! Locusts! It wasn’t my fault! I SWEAR TO GOD!
Good lord, now I’m wondering if David was a paranoid schizophrenic, the way he keeps whining about having so many enemies. And as a paterfamilias, I bet he was chock-full of inner demons.
This is yet another psalm in which David wants YHWH to deliver him from what he fears, maybe to justify his own bad deeds. The devil couldn’t make him do it if he was on a mission from YAH.
