The laws of a Nazirite teach us a most significant principle about our belief in the coming of Moshiach.

Halachah (Torah-law) decrees: If one declares, “I undertake to become a Nazirite on the day that Moshiach will come,” then if he made this vow on a weekday he is forever bound by it from that very moment. If he made his vow on a Shabbat or Yom Tov (festival-day), it will become operative from the next day onwards, forever, but not on that day itself. For it is uncertain whether Moshiach will or will not come on a Shabbat or Yom Tov, which, therefore, precludes making the vow operative on that day (Eruvin 43b; Hilchot Nezirut 4:11).

This demonstrates clearly the fact that “the day that Moshiach will come” is a possibility that applies to each day. Thus we say in our daily prayers, “every day (and all day long) we hope for Your salvation”; or in the version of the Thirteen Principles of the Faith: “I await his coming every day.”
