Halakha Imamat 23:24: Mishneh Torah, Rest, Mishneh Torah, The Chosen Temple, Mishneh Torah, Prayer and the Priestly Blessing & Mishneh Torah, Shofar, Sukkah and Lulav

Anyone who rests from work of labor on one of them has surely fulfilled a positive commandment; as it is surely stated about them (Leviticus 23:24), "a day of rest (shabbaton)" -meaning to say, "Rest!" And anyone who does work on one of them which is not for the sake of eating—such as [if] he built or demolished or wove or that which is similar to these—has surely negated a positive commandment and violated a negative commandment, as it is stated (Exodus 12:17), "no work shall be done on them." And if one did it [in front of] witnesses and with a warning, he is lashed from Torah writ.

The Temple is not to be built at night as it says "and on the day the Tabernacle was erected," i.e. we erect it during the day but not at night. We may work on the construction from dawn until the stars come out, and everyone is obligated to build helping physically and financially both men and women just like the sanctuary in the desert. However, we do not close the schools in order [for the children] to build the Temple nor does building the Temple override Shabbat or the festivals.

The foregoing statement applies to the evening, morning and afternoon services of the New Year. But the additional service on the New Year consists of nine blessings; the first three and the last three recited daily, and three Intermediate. Of these intermediate benedictions, the theme of the first is God's Sovereignty; of the second His remembrance; while the third has references to the Shofar. Each of these blessings concludes with a formula appropriate to its theme.
