"חרבה קסרי וישבה ירושלים.. תאמן"

אם יאמר לך אדם חרבו שתיהן אל תאמן ישבו שתיהן אל תאמן חרבה קסרי וישבה ירושלים חרבה ירושלים וישבה קסרי תאמן
(בבלי מגילה ו ע"א)

Megillah 6a: "If someone tells you 'both are in ruins' don't believe them, 'both are standing' don't believe them, 'Caesarea is destroyed and Jerusalem is standing' or 'Jerusalem in destroyed and Caesarea is standing' believe them."

Right before Hakofos, Simchas Torah night, 1972, two weeks after the outbreak of the Yom Kippur War, Aryeh Morgenstern visited the Lubavitcher Rebbe along with some colleagues from the Israeli Consulate.
