Kings III 6:4

4 And he made to the house secret windows inclining inward.

Kings III 6:4 In-Context

2 And the house which the king built to the Lord forty cubits in length, and twenty cubits in breadth, and its height five and twenty cubits.
3 And the porch in front of the temple—twenty cubits its length according to the breadth of the house in front of the house: and he built the house, and finished it.
4 And he made to the house secret windows inclining inward.
5 And against the wall of the house he set chambers round about the temple and the ark.
6 The under side five cubits broad, and the middle six, and the third seven cubits broad; for he formed an interval to the house round about without the house, that they might not touch the walls of the house.
