Rosh Hashanah ראש השנה

Numbers 29:1-6

וּבַחֹדֶשׁ הַשְּׁבִיעִי בְּאֶחָד לַחֹדֶשׁ מִקְרָא־קֹדֶשׁ יִהְיֶה לָכֶם כָּל־מְלֶאכֶת עֲבֹדָה לֹא תַעֲשׂוּ יוֹם תְּרוּעָה יִהְיֶה לָכֶם׃

^29:1 And in the seventh month, on the first day of the month, ye shall have a holy convocation: ye shall do no manner of servile work; it is a day of blowing the horn unto you.

וַעֲשִׂיתֶם עֹלָה לְרֵיחַ נִיחֹחַ לַיהוָה פַּר בֶּן־בָּקָר אֶחָד אַיִל אֶחָד כְּבָשִׂים בְּנֵי־שָׁנָה שִׁבְעָה תְּמִימִם׃

^29:2 And ye shall prepare a burnt-offering for a sweet savour unto the LORD: one young bullock, one ram, seven he-lambs of the first year without blemish;

וּמִנְחָתָם סֹלֶת בְּלוּלָה בַשָּׁמֶן שְׁלֹשָׁה עֶשְׂרֹנִים לַפָּר שְׁנֵי עֶשְׂרֹנִים לָאָיִל׃

^29:3 and their meal-offering, fine flour mingled with oil, three tenth parts for the bullock, two tenth part for the ram,

וְעִשָּׂרוֹן אֶחָד לַכֶּבֶשׂ הָאֶחָד לְשִׁבְעַת הַכְּבָשִׂים׃

^29:4 and one tenth part for every lamb of the seven lambs;

Continues in the lesson.

JPS 1917 and Tanach with Nikkud, public domain, via Sefaria

The Torah never says “Rosh Hashanah” (head of the year). It describes the first day of the seventh month as a day of blowing the horn. This passage is read in synagogue on the holiday.
