Introduction:
Amaziah, the son of Joash, was the ninth king of Judah, whose reign is chronicled in the biblical books of 2 Kings 14:1-20 and 2 Chronicles 25. His rule is marked by a mixture of fidelity to God and significant failures, reflecting the complexities of leadership in the divided monarchy period.

Background:
Amaziah ascended to the throne following the assassination of his father, Joash. He began his reign at the age of 25 and ruled for 29 years in Jerusalem. His mother's name was Jehoaddan of Jerusalem (2 Kings 14:2).

Religious Observance:
Amaziah is noted for doing "what was right in the eyes of the LORD, yet not like his father David" (2 Kings 14:3). He adhered to the worship of Yahweh but did not remove the high places, where the people continued to offer sacrifices and burn incense (2 Kings 14:4). This partial obedience is a recurring theme in the narrative of Judah's kings, highlighting the ongoing struggle between true worship and syncretism.

Military Campaigns:
Amaziah's reign included notable military endeavors. He successfully waged war against the Edomites, capturing Sela and renaming it Joktheel (2 Kings 14:7). This victory, however, led to a spiritual downfall as he brought back the gods of the Edomites and worshiped them, provoking the LORD's anger (2 Chronicles 25:14-15).

Conflict with Israel:
Amaziah's pride following his victory over Edom led him to challenge Jehoash, king of Israel. Despite a warning from Jehoash, Amaziah insisted on battle, resulting in a disastrous defeat at Beth-shemesh. Jehoash captured Amaziah, broke down the wall of Jerusalem, and plundered the temple and royal palace (2 Kings 14:8-14).

Later Years and Death:
Amaziah's later years were marked by conspiracy and unrest. After a period of instability, a conspiracy was formed against him in Jerusalem, prompting him to flee to Lachish. However, he was pursued and killed there (2 Kings 14:19). His body was brought back to Jerusalem and buried with his ancestors in the City of David (2 Kings 14:20).

Legacy:
Amaziah's reign is a testament to the challenges of maintaining faithfulness to God amidst political and military pressures. His initial obedience, marred by idolatry and pride, serves as a cautionary tale about the dangers of incomplete devotion and the consequences of turning away from God. His account is a reminder of the importance of wholehearted commitment to the LORD, as exemplified by his ancestor David.
