The followings elements are essential when constructing this House:
a) the Sanctuary,
b) the Holy of Holies,
c) preceding the Sanctuary, there should be a place called the Entrance Hall.
The three [together] are called the Temple.

[In addition,] we must make another partition around the Temple, set off from it [slightly], resembling the curtains surrounding the courtyard of the [sanctuary in the] desert. Everything encompassed by this partition is similar to the courtyard of the Tent of Meeting and is called the Courtyard.

The entire area is referred to as the Mikdash.
