1 Kings 3:2-4

Young's Literal Translation

² Only, the people are sacrificing in high places, for there hath not been built a house for the name of Jehovah till those days.

³ And Solomon loveth Jehovah, to walk in the statutes of David his father -- only, in high places he is sacrificing and making perfume --

⁴ and the king goeth to Gibeon, to sacrifice there, for it [is] the great high place; a thousand burnt-offerings cause to ascend doth Solomon on that altar.
