1 Kings 11:6-8, 9-10

Solomon openly defied GOD; he did not follow in his father David’s footsteps. He went on to build a sacred shrine to Chemosh, the horrible god of Moab, and to Molech, the horrible god of the Ammonites, on a hill just east of Jerusalem. He built similar shrines for all his foreign wives, who then polluted the countryside with the smoke and stench of their sacrifices.

GOD was furious with Solomon for abandoning the GOD of Israel, the God who had twice appeared to him and had so clearly commanded him not to fool around with other gods. Solomon faithlessly disobeyed GOD’s orders.
