This is yet another waste of time. Here Jehovah is saying "I don't have to do a fxxxing thing for you, since I already provided the blueprint in Tyrant David. Instead of viewing your own miserable, unfulfilled life, you are to dwell on what I did for Tyrant David."
I have some bad news for you. Just because Jehovah did something for Tyrant David (or Job, for that matter), THAT DOES NOT MEAN JACK SQUAT FOR YOU. The "blessing" was already done and written up so that Almighty Lowlife Scumbag won't have to endure yet another life marred by happiness and pleasure repeating it on you. Instead, you are supposed to dwell on the life of someone (or several other people) that died more than 3,000 years ago.
