I had a bit of a realization regarding this passage. In my youth, I heard Phyllis Diller say this meant, “Stay up and fight!” which was a comic line that got a laugh. Funny how things you hear in your youth can pollute the meaning.
I think she’s almost right (and she probably knew it), but this morning’s thought is: don’t nurture and burnish your anger. It’s false comfort to do so. You may not get your issue resolved, but you should at least bring it up for discussion. Anyway, anger is a secondary emotion. It comes from something else, like hurt, fear, a sense of injustice, etc. It’s ok to be angry, but watch what you do with your anger. And maybe be aware of what’s under/behind it by the time you go to sleep, since sleeping on it might sort of cement it in place.
I know, blithe statements from the Bible and (pseudo-) wisdom from a fool. But, still.
Also, from one commentary (Oxford Bible Commentary), on “deceitful desires”: “the desire which constantly promises but never fully satisfies.” Hmm. Like… burnished anger?
