Is there any significance to this short psalm sharing 4 rare words with Job?
Verse 2 alone shares its two rare words in 10 verses of Job. It is not hard to imagine the threat of such 'darkness' or 'obscurity' in this formative portion of Job 3:6
The night - that night, let אֹפֶל seize it
al-yixad biyomei shana bemispar yeraxim al-yabo
Let it have no joy in the days of the year
into the number of the months of the year let it not come
tixadhu bsimxah et-paneyka
you have filled him with the joy of your presence
[Update: I note more connections between Job and the psalms here]. And what about that preposition, בְּמוֹ? Seems to be just a preposition - translatable by just about any English preposition that you want to chose: At in into through with or for. (It is one of the few prepositions that BLB bothers to enumerate.)
Eyelids occurs in close proximity to אֹפֶל in Job 3:9 - here as the dawn of the day, the fluttering of the eyelids of the sun. Mostly, as in Psalm 11:4 and Psalm 132:4 it is used in parallel with eyes.
Verse 6 touches on Sodom and Hell of course. Where else do you find brimstone and burning heat? (Well - to tell you the truth, fire is omnipresent.) As to portion, perhaps we will return to this when we get to Psalm 63. That's enough free-association for today.
