M. Ramsay has found a number of these in the letters to the seven churches (Rev 2-3). Some examples:
–Sardis
was never taken by storm, but only by stealth at night (cp Rev 3:3).
–Laodicea
was plagued with a water supply which was only lukewarm by the time it reached the city
(cp Rev 3:16).
–These
are not controversial.
