1 Kings 3:3-4

3Now Solomon loved the Lord, walking [at first] in the statutes of David his father, except [for the fact that] he sacrificed and burned incense in the high places [ignoring the law that required all sacrifices to be offered at the tabernacle].

4The king went to Gibeon [near Jerusalem, where the tabernacle and the bronze altar stood] to sacrifice there, for that was the great high place. Solomon offered a thousand burnt offerings on that altar.
