1 Kings 6:8-10

New Catholic Bible

⁸ The entrance for the lowest level was on the right side of the temple. One went up by stairs from there to the middle level, and from the middle to the third level. ⁹ Thus he built the temple and completed it by roofing it with beams and cedar planks.

¹⁰ He built side rooms all along the temple. They were five cubits high, and they were attached to the temple with cedar beams.
