The psalm addresses the spiritual danger that lurkes at all times, but here specially at night and noonday.Pakh => Snare = bait, plot, agent of calamity
Yawkoosh => fowler = trapper, bait layer
Deber => pestilence, plague, disease - the same as what was dished out the the Egyptians, and threatened to Israel and dished out to Israel in the final days before they were exiled the first time.
Pachad Pakh’ - Ad => Terror, Dread feel extreme reluctance to meet or face same as phobos as in hearts fail
pachad lahyil => fear of the night - this is the name of a fearsome demon causing night paralysis
Khayts => arrow that flies in daytime
Deber walking in darkness? that can only be a living being as pestilence does not "walk"
Destruction the ruins at midday.
The satan is a deceiver that lures people into sin, so is an idolatrous, lustful, unfaithful, adulterous woman - giving in to any leads to ruin.
