Total Envelopment: Interpreting "Covering All"

The expression "covering all" in the context in which it is used conveys the idea of a complete, all-encompassing action – an effect where nothing remains outside of its influence, when something covers or envelops every aspect. That is, it is not merely a partial effect or manifestation, but a total envelopment, where every part of an object or situation is permeated or filled by a single, unified force.

Thus, in one excerpt (although the expression is phrased somewhat differently here), an image is used of a night that completely shrouds the unbelieving world:
"And there was night... And behold, this night covers the unbelieving world..." (source: link txt)

This example demonstrates that "covering" here means to completely envelop, to seize everything around. Similarly, when another text speaks about inflicting wounds, the phrase "covering with wounds" emphasizes that the impact deprives every part (in this case – the body) of any remaining state of integrity, even if it was already depleted (source: link txt).

Thus, the expression "covering all" implies an inseparable and total penetration or imposition of some action, state, or influence, leaving nothing aside. This can be either a literal physical covering (for example, as night covers the world) or a metaphorical one, symbolizing total enveloping or influence on a situation or individual.
