1 Kings 6:32

The two doors. — Those into the Holy place from the porch, of cypress wood, were naturally made larger. The posts were a fourth of the wall. Hence, according as the wall is taken to be 20 cubits square, or 30 cubits high by 20 wide, the height would be 5 cubits (7½ feet), or 7½ cubits (11¼ feet). The width is not given; possibly it is taken to be the same as that of the other doors. As these doors would be much heavier, and more frequently opened and shut, each leaf was made to fold again upon itself.
