Paradox #1
The contradiction or inconsistency related to Isaiah 11:13 could be the reference to the division and eventual reconciliation between Ephraim (representing the northern kingdom of Israel) and Judah (representing the southern kingdom). Historically, these two kingdoms had conflicts and divisions after the reign of King Solomon, and complete reunification as described in the verse is not clearly documented in historical records.
