Rev 11:2

2 Leave out the court which is outside of the temple, and don’t measure it, for it has been given to the gentiles. They will tread the holy city under foot for forty-two months. 

leave out the court which is outside – here the word “court” is the same word we might use for court. It is used in Matt 26:3 and John 18:15, to describe the court of the high priest, where Jesus was tried.

and don’t measure it for it has been given to the Gentiles – in the giving of the measurements of the Temple in Ezekiel, no measurements were made of the outside court, because of course, this Temple was to be for all nations. But as explained below, the Gentiles will trample the Holy City underfoot and once again be excluded from the Temple, excluded from the sanctified Church. 

they will tread the Holy City underfoot for 42 months – the Gentiles trampled the Gospel for 42 months, which are 1278 days, 1278 years, from 193 until 1471, when the first Protestant Church broke free from the Papacy.
