2 Kings 21
Manasseh succeeds his father Hezekiah as 
of Judah & his legacy 
…..
He did what was evil in the Lord ’s sight, following the detestable practices of the pagan nations that the Lord had driven from the land ahead of the Israelites. He built pagan altars in the Temple of the Lord , the place where the Lord had said, “My name will remain in Jerusalem forever.” Manasseh also sacrificed his own son in the fire. He practiced sorcery and divination, and he consulted with mediums and psychics. He did much that was evil in the Lord ’s sight, arousing his anger.
Manasseh also murdered many innocent people until Jerusalem was filled from one end to the other with innocent blood. This was in addition to the sin that he caused the people of Judah to commit, leading them to do evil in the Lord ’s sight.
