Because Manasseh, king of Judah, has done these disgusting things, doing more evil than all the Amorites before him, and making Judah do evil with his false gods,

Moreover Manasseh shed innocent blood very much, till he had filled Jerusalem from one end to another; beside his sin wherewith he made Judah to sin, in doing that which was evil in the sight of the LORD.

He made his son pass through the fire, practiced soothsaying and divination, and dealt with mediums and spiritists. He increased the doing of evil in the eyes of Yahweh to provoke him.

And they made their sons and their daughters go through the fire, and they made use of secret arts and unnatural powers, and gave themselves up to doing evil in the eyes of the Lord, till he was moved to wrath.

He did what the LORD considered to be evil, after the pattern of Nebat's son Jeroboam. By doing so, he caused Israel to sin, and he never changed course from it.

He did what the LORD considered to be evil. Just as Nebat's son Jeroboam had led Israel into sin, so also Pekahiah did not stop doing the same thing.
