1 Kings 3:2-4

Living Bible

² At that time the people of Israel sacrificed their offerings on altars in the hills, for the Temple of the Lord hadn’t yet been built.

³ (Solomon loved the Lord and followed all of his father David’s instructions except that he continued to sacrifice in the hills and to offer incense there.) ⁴ The most famous of the hilltop altars was at Gibeon, and now the king went there and sacrificed one thousand burnt offerings!
