Halakhah for Berakhot 122:18

From the laws of the commandment is that which they, may their memory be blessed, said (Megillah 28b) that a person may only enter any of the Temple Mount for the matter of a commandment. And anyone who has finished his service in the [Temple] and retires, walks backwards a little at a time; and so [too,] the men of the shift, the men of the watch and the Levites from their platforms, would leave like this from the Temple. And [also] that which they, may their memory be blessed, said (Berachot 61b) [that] it is always forbidden to defecate or sleep between east and west, because the Sanctuary is in the West. And so [too,] (Rosh Hashanah 24a) is it forbidden for a person to build a house in the form of the Sanctuary, nor a portico in the form of the chamber nor a courtyard in the form of the [Temple] yard. And all of this is from the awe of the place. And the rest of the details of the honor of the [Temple] and its awe are in Middot and Tamid (see Mishneh Torah, Laws of The Chosen Temple 7).
