The three weeks known as Bein HaMeitzarim, twenty-one days between 17th of Tamuz and 9th of Av, are marked by abstaining from wedding ceremonies, dance-music, and for the more observant: no eating of meat or drinking wine, except on Shabbat. We read in Mishna, Ta'anit 4.6: 'Five things befell our ancestors on the 17th of Tamuz, and five on the 9th of Av'. The two lists of five things are somewhat symmetric: the first event in each list connects these two dates with mishaps during the first years of wandering in the Sinai desert, following the Exodus. The second and third items in each of these two lists connect the two dates with commemorating the destruction of the Temple in Jerusalem. Which of the two Temples: the first or the second? As for Tish'ah beAv this mishnah is clear: 'The Temple was destroyed the first time and the second time on this date', i.e. both Temples were destroyed on the same date in different centuries. There is a contradiction between the two Biblical reports, in Jeremiah 52:12 and in II Kings 25:8, concerning the First Temple.
