Counter-Arguments

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

Israel-Specific Promises

While the verse describes a period of peace for Israel, it is a historical account of an event and its immediate consequence, not a promise, prophecy, or covenant directed at Israel for the future.

Time-Bound Fulfillment

The verse describes a period of peace after a military victory, not the fulfillment of a prophecy with a defined duration. The "forty years" is a historical detail of the duration of peace, not a pre-stated prophetic timeline.
