2 Samuel 5:2

The verse describes a historical event and a divine promise made to David concerning his leadership over the nation of Israel *at that time*. While it clearly distinguishes Israel as a people over whom David would rule, it doesn't inherently make claims about Israel's future prophetic role or a land covenant separate from the Church in a theological sense. The "distinctness" here is primarily in the context of a national and political entity under a specific king, rather than a theological state

While the verse speaks of David leading and feeding Israel, which implies a promise to Israel through David, the primary promise articulated here is to David himself ("Thou shalt feed my people Israel, and thou shalt be a captain over Israel"), rather than a direct promise *to* Israel.
