Luke 16. Jesus told the parable of the unjust steward to show it is not enough to follow the practices of the land, one must be above reproach in spiritual things, even if you are following the Law and the Prophets to the letter you will fail. He ended with the parable of the rich man and Lazarus.
1 Kings 12 tells of the revolt against Rehoboam and Jeroboam’s Golden Calves at Bethel and Dan. They were put up so Rehoboam didn’t have to go to Jerusalem to sacrifice.
1 Kings 13. From Judah came a Man of God with a message. It did not go over well, so through lies and intrigues the Man of God was killed by a lion. One quote from this chapter: “After this thing Jeroboam returned not from his evil way, but made again of the lowest of the people priests of the high places: whosoever would, he consecrated him, and he became one of the priests of the high places.” Large portions of the Old Testament describes how not to worship, let this be a warning for us.
