2 Kings 3:1-3 “In the eighteenth year of Jehoshaphat king of Judah, Jehoram the son of Ahab became king over Israel in Samaria, and he reigned twelve years. He did what was evil in the sight of the LORD, though not like his father and mother, for he put away the pillar of Baal that his father made. Nevertheless, he clung to the sin of Jeroboam the son of Nebat, which he made Israel to sin; he did not depart from it.”
Almost 100 years since Jeroboam set up the two calves and prohibited the people from going to Jerusalem to worship and they are still struggling with this sin. Jeroboam probably thought that his little worship system was only a temporal fix until something else could get put in place but here it keeps showing up. Worse still, when people commit this sin he is referenced every time, so every time a king falls into this the text makes reference to Jeroboam. Not a good reason to be in the Bible.
Additionally, 1 and 2 Kings often refers to the sons reign (whether good or bad) in terms of how they followed their father. If he was a good king and he did good then he walked in the way of the father. If he was a bad king and the father was good, then the son did not walk in the way of the father. This started with Solomon and progresses through 1 and 2 Kings. Interesting how the father influences the children.
