And moreover,לפני השם (before the LORD) is said about any place which has no equal. Sometimes, it means the Inner Sanctuary. And sometimes the Temple. And it sometimes refers to all of the Temple, and sometimes the east side of the altar, and sometimes its north side, and sometimes its west side, and sometimes the eastern gate of the Temple Court, and sometimes all of Jerusalem.

And I clarified that in holiness there are many levels, and any place called לפני השם has a higher level of holiness, and it is interpreted everywhere according to its context. And this is clarified in my book Torah Ohr at length.

And any place where it says לפני השם, it excludes a private altar.
