1 Kings 6:7-8

7When they built the temple, they used stones that were the right shape. Workers had already cut the stones at the place where they came from. There was no sound of hammers, axes or any iron tools at the place of the temple.

8The door to the lowest level of rooms on the sides of the temple was on the south side of the temple. Stairs went up to the middle level and to the top level.
