Paradox #1
The contradiction might be related to the timeline of King Jehoash's reign compared to other biblical records, leading to discrepancies in the chronology of kings of Judah and Israel.
Paradox #2
2 Kings 12:1 mentions the reign of Jehoash beginning in the seventh year of Jehu's reign. However, comparing it with 2 Kings 13:1, it indicates that Jehoash of Judah and Jehoahaz of Israel began their reigns at different times in the context of Jehu's timeline, which could seem inconsistent.
