“No outsider shall enter the protective enclosure around the sanctuary. And whoever is caught will only have himself to blame for his ensuing death.”

Now THAT is well-written copy.

As noted by this traveler, the famed Temple in Jerusalem (destroyed by Romans in 70 A.D.)  announced Gentiles couldn’t cross into the sanctuary without risking death.  Historian Josephus commented on these signs in his histories, and archeologists unearthed one of them in 1871.
