1 Kings 3:1-4

Then Solomon formed a marriage alliance with Pharaoh king of Egypt, and took Pharaoh’s daughter and brought her to the city of David until he had finished building his own house and the house of the LORD and the wall around Jerusalem. The people were still sacrificing on the high places, because there was no house built for the name of the LORD until those days. Now Solomon loved the LORD, walking in the statutes of his father David, except he sacrificed and burned incense on the high places. The king went to Gibeon to sacrifice there, for that was the great high place; Solomon offered a thousand burnt offerings on that altar.
