2 Chronicles 33:16
And he repaired the altar of the LORD, and sacrificed thereon peace offerings and thank offerings, and commanded Judah to serve the LORD God of Israel. And he repaired the altar of the LORD, and sacrificed thereon peace offerings and thank offerings, and commanded Judah to serve the LORD God of Israel.
Manasseh was born during the fifteen years added to Hezekiah's life after Hezekiah prayed for longer life, became one of the wickedest kings Judah ever had, and reigned fifty-five years, one of the longest reigns. After he was taken prisoner by the Assyrians he humbled himself, learned to know God, and God restored him from captivity to his kingdom and dominions and accepted him, making him a marvelous instance of God's wonderful mercy.
His repentance took practical form in an effort to reform the kingdom and undo his former evil deeds and the profanations he had brought upon the Lord's house. He removed the idols and false altars, repaired the altar of the LORD, sacrificed peace offerings and thank offerings on it, and commanded Judah to serve the LORD God of Israel. The effects of his earlier evil were not wholly undone.
As part of Chronicles, the verse gives a concrete historical example of how God's principles work, showing that God regards people who long to do His will. Falling within the events leading to the Babylonian captivity, it shows that temple ritual by itself is not true religion; when worship becomes merely ritual and light is rejected, it becomes Babylonish in character, and Babylon triumphs over its people.
