1 Kings 3:2-4

MLV(i) 2 Only the people sacrificed in the high places, because there was no house built for the name of Jehovah until those days.
3 And Solomon loved Jehovah, walking in the statutes of David his father. Only he sacrificed and burnt incense in the high places. 4 And the king went to Gibeon to sacrifice there, for that was the great high place. Solomon offered a thousand burnt offerings upon that altar.
