The Chronicler selected three events from Amaziah's reign to teach important spiritual lessons.
First, Amaziah followed the Mosaic Law faithfully in dealing with the people who had killed his father (vv. 1-4; cf. Deut. 24:16). These actions transpired at the beginning of his reign.
Second, the king obeyed God partially in his war with the Edomites (vv. 5-16). He unwisely hired mercenary soldiers from Israel to help him rather than seeking the Lord's help (v. 6). However when the prophet rebuked him, he obediently dismissed them even though it cost him 7,500 pounds of silver (v. 10). Nevertheless because he had hired them, he not only lost his money but he also lost the lives of some of his soldiers when the Edomites retaliated for having been dismissed (v. 13). Furthermore he disobeyed Yahweh by importing the gods of Edom (v. 14). Finally he refused to repent (v. 10).68
Third, Amaziah disobeyed God by attacking Israel late in his reign (vv. 17-24). This was due, from the divine perspective, to the king's idolatry (v. 20) and, from the human perspective, to his pride (v. 18).69The consequences were that Judah's enemy destroyed a portion of the wall around Jerusalem (God removed its defense, v. 23), and stripped the temple (the glory of God diminished, v. 24).
"At bottom, it is the breakdown in the relationship between Amaziah and God which causes his downfall."70
Idolatry was a serious matter because it struck at the heart of God's relationship with His people. God blessed Israel with the opportunity to have intimate personal relationship with the living sovereign Lord as no other people in the world then. To turn from this privilege to pursue dead idols was the height of effrontery (cf. Exod. 20:5). From the time Amaziah turned from Yahweh, God began to turn against him by using the faithful in Judah as His instruments of judgment (v. 27). "The city of Judah"(v. 28) is a later name for Jerusalem (cf. 2 Kings 14:20).
"Instead of royal building programs, the walls of Jerusalem are destroyed; instead of wealth from the people and surrounding nations, the king is plundered; instead of a large family, there were hostages; instead of peace, war; instead of victory, defeat; instead of loyalty from the populace and long life, there is conspiracy and regicide."71
