Counter-Arguments

The strongest case that this verse does not belong in this theme.

Time-Bound Fulfillment

The verse describes a past event with a duration ("three days") but does not present this duration as a prophecy or a fulfillment of a prophecy. It is a factual statement about the elapsed time of their journey, not a prediction with a defined duration to be recognized upon its completion.
