Unlike his father who would protect the people of Judah, Manasseh would burn them as sacrifices to idols. Unlike his father who loved God and restored the temple, Manasseh showed his irreverence by erecting idols of false gods in the temple. God would not tolerate all of this abuse and irreverence and so He allowed him to be bound and taken prisoner by the King of Assyria. While there, Manasseh humbled himself and cried out to God. And God who is rich in mercy and steadfast love, received his prayer and restored his kingdom.
