#3, achake loi bechol yom sheyavoi. Period. Don’t doubt it for one second that Moshiach won’t come tomorrow. Part of the Ikrei Haemunah.
If it was an Ikar of Emunah yesterday that Moshiach would
come today, what now? Obviously, that is a misinterpretation.
It means to wait in anticipation for him to come, not to
believe that he is definitely coming at any specific time.
