sonnez le Chofar à la nouvelle lune, au jour fixé pour notre solennité.

Mishneh Torah, Sanctification of the New Month

Thereupon, when the evidence has been sustained, the chief justice of the court proclaims Mekuddash! [the new moon is sanctified], and after him all the people present respond: Mekuddash! Mekuddash! Only a court of three may carry out the calculation and the sanctification of the new moon. The formal sanctification of the new moon is proclaimed only when the new moon has been observed in its proper time; and this must be done at daytime. If it was done at night, the sanctification is not valid. And even if the court and all of Israel saw it, but the court didn't say, "[It is] sanctified," until it became dark on the night of the thirty-first; or they investigated the witnesses and the court didn't manage to say, "[It is] sanctified," until it became dark on the night of the thirty-first – they don't sanctify it; and the month will be intercalated, and Rosh Chodesh (the first of the month) will only be on the thirty-first – even though it was seen on the night of the thirtieth. For it is not the sighting that sets [it], but rather it is the court saying, "[It is] sanctified," that sets [it].

Mishneh Torah, Shofar, Sukkah and Lulav

We may not mention malkhiot, zikhronot and shofarot of punishment — such as [in] zikhronot, "And all flesh shall remember that, etc." (Psalms 78:39); [in] malkhiot, "with outpoured anger shall I rule over you" (Ezekiel 20:33); [and in] shofarot, "Blow the shofar on the mountain, etc." (Hosea 5:8). Nor [may we mention] the remembrance of an individual — even if it was for good — such as "Remember me, O Lord, in the desire of Your people" (Psalms 106:4); and "Remember me, my God, for the good" (Nehemiah 13:31). And recollections (pikdonot) — such as "I have surely recalled you" (Exodus 3:16) — are not the same as remembrances. But one may mention the punishment of idolatrous nations, such as "The Lord reigned, nations tremble" (Psalms 99:1); "Remember the day of Jerusalem to the Children of Edom" (Psalms 137:7); [and] "the Lord, God, will blow with the shofar, and go in the storms of the south" (Zechariah 9:14). All of these verses: "Hear Israel, the Lord, our God, the Lord is one" (Deuteronomy 6:4); "You have been shown to know" (Deuteronomy 4:35); "And you shall know today and place upon your hearts, etc." (Deuteronomy 4:39) — their content is kingship. Even though there is no mention of kingship [in them], it is surely like, "The Lord will reign forever and ever" (Exodus 15:18); [and] "And then He became King in Jeshurun, etc." (Deuteronomy 33:5).
