1 Kings 6:2

In the four hundred and eightieth year after the children of Israel had come out of the land of Egypt, in the fourth year of Solomon’s reign over Israel, in the month Ziv, which is the second month, he began to build the LORD’s house.

The porch in front of the temple of the house had a length of twenty cubits, which was along the width of the house. Ten cubits was its width in front of the house.

He made windows of fixed lattice work for the house.

Against the wall of the house, he built floors all around, against the walls of the house all around, both of the temple and of the inner sanctuary; and he made side rooms all around.
