1 Kings 3:2-5

The people were sacrificing at the high places, however, because no house had yet been built for the name of the LORD. Solomon loved the LORD, walking in the statutes of David his father, only he sacrificed and made offerings at the high places. And the king went to Gibeon to sacrifice there, for that was the great high place. Solomon used to offer a thousand burnt offerings on that altar. At Gibeon the LORD appeared to Solomon in a dream by night, and God said, “Ask what I shall give you.”
