12 But while in deep distress, Manasseh sought the Lord his God and sincerely humbled himself before the God of his ancestors. 13 And when he prayed, the Lord listened to him and was moved by his request. So the Lord brought Manasseh back to Jerusalem and to his kingdom. Then Manasseh finally realized that the Lord alone is God! 14 After this Manasseh rebuilt the outer wall of the City of David, from west of the Gihon Spring in the Kidron Valley to the Fish Gate, and continuing around the hill of Ophel. He built the wall very high. And he stationed his military officers in all of the fortified towns of Judah. 15 Manasseh also removed the foreign gods and the idol from the Lord 's Temple. He tore down all the altars he had built on the hill where the Temple stood and all the altars that were in Jerusalem, and he dumped them outside the city. 16 Then he restored the altar of the Lord and sacrificed peace offerings and thanksgiving offerings on it. He also encouraged the people of Judah to worship the Lord, the God of Israel. 17 However, the people still sacrificed at the pagan shrines, though only to the Lord their God. 18 The rest of the events of Manasseh's reign, his prayer to God, and the words the seers spoke to him in the name of the Lord, the God of Israel, are recorded in 19 Manasseh's prayer, the account of the way God answered him, and an account of all his sins and unfaithfulness are recorded in It includes a list of the locations where he built pagan shrines and set up Asherah poles and idols before he humbled himself and repented. 20 When Manasseh died, he was buried in his palace. Then his son Amon became the next king.

Commentary on 2 Chronicles 33:1-20

(Read 2 Chronicles 33:1-20)

We have seen Manasseh's wickedness; here we have his repentance, and a memorable instance it is of the riches of God's pardoning mercy, and the power of his renewing grace. Deprived of his liberty, separated from his evil counsellors and companions, without any prospect but of ending his days in a wretched prison, Manasseh thought upon what had passed; he began to cry for mercy and deliverance. He confessed his sins, condemned himself, was humbled before God, loathing himself as a monster of impiety and wickedness. Yet he hoped to be pardoned through the abundant mercy of the Lord. Then Manasseh knew that Jehovah was God, able to deliver. He knew him as a God of salvation; he learned to fear, trust in, love, and obey him. From this time he bore a new character, and walked in newness of life. Who can tell what tortures of conscience, what pangs of grief, what fears of wrath, what agonizing remorse he endured, when he looked back on his many years of apostacy and rebellion against God; on his having led thousands into sin and perdition; and on his blood-guiltiness in the persecution of a number of God's children? And who can complain that the way of heaven is blocked up, when he sees such a sinner enter? Say the worst against thyself, here is one as bad who finds the way to repentance. Deny not to thyself that which God hath not denied to thee; it is not thy sin, but thy impenitence, that bars heaven against thee.
