(כד) דַּבֵּר אֶל בְּנֵי יִשְׂרָאֵל לֵאמֹר בַּחֹדֶשׁ הַשְּׁבִיעִי בְּאֶחָד לַחֹדֶשׁ יִהְיֶה לָכֶם שַׁבָּתוֹן זִכְרוֹן תְּרוּעָה מִקְרָא קֹדֶשׁ. (כה) כָּל מְלֶאכֶת עֲבֹדָה לֹא תַעֲשׂוּ וְהִקְרַבְתֶּם אִשֶּׁה לַיהוָה.

(24) Speak unto the children of Israel, saying: In the seventh month, in the first day of the month, shall be a solemn rest unto you, a memorial proclaimed with the blast of horns, a holy convocation. (25) Ye shall do no manner of servile work; and ye shall bring an offering made by fire unto the LORD.

(א) וּבַחֹדֶשׁ הַשְּׁבִיעִי בְּאֶחָד לַחֹדֶשׁ מִקְרָא קֹדֶשׁ יִהְיֶה לָכֶם כָּל מְלֶאכֶת עֲבֹדָה לֹא תַעֲשׂוּ יוֹם תְּרוּעָה יִהְיֶה לָכֶם.

(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.
אמר רבי אבהו למה תוקעין בשופר של איל אמר הקדוש ברוך הוא תקעו לפני בשופר של איל כדי שאזכור לכם עקידת יצחק בן אברהם ומעלה אני עליכם כאילו עקדתם עצמכם לפני

Similarly, Rabbi Abbahu said: Why does one sound a blast with a shofar made from a ram’s horn on Rosh HaShana? The Holy One, Blessed be He, said: Sound a blast before Me with a shofar made from a ram’s horn, so that I will remember for you the binding of Isaac, son of Abraham, in whose stead a ram was sacrificed, and I will ascribe it to you as if you had bound yourselves before Me.

(יג) וַיִּשָּׂ֨א אַבְרָהָ֜ם אֶת־עֵינָ֗יו וַיַּרְא֙ וְהִנֵּה־אַ֔יִל אַחַ֕ר נֶאֱחַ֥ז בַּסְּבַ֖ךְ בְּקַרְנָ֑יו וַיֵּ֤לֶךְ אַבְרָהָם֙ וַיִּקַּ֣ח אֶת־הָאַ֔יִל וַיַּעֲלֵ֥הוּ לְעֹלָ֖ה תַּ֥חַת בְּנֽוֹ׃
(13) And Abraham lifted up his eyes, and looked, and behold behind him a ram caught in the thicket by his horns. And Abraham went and took the ram, and offered him up for a burnt-offering in the stead of his son.
(טז) וַיְהִי֩ בַיּ֨וֹם הַשְּׁלִישִׁ֜י בִּֽהְיֹ֣ת הַבֹּ֗קֶר וַיְהִי֩ קֹלֹ֨ת וּבְרָקִ֜ים וְעָנָ֤ן כָּבֵד֙ עַל־הָהָ֔ר וְקֹ֥ל שֹׁפָ֖ר חָזָ֣ק מְאֹ֑ד וַיֶּחֱרַ֥ד כָּל־הָעָ֖ם אֲשֶׁ֥ר בַּֽמַּחֲנֶֽה׃ (יז) וַיּוֹצֵ֨א מֹשֶׁ֧ה אֶת־הָעָ֛ם לִקְרַ֥את הָֽאֱלֹהִ֖ים מִן־הַֽמַּחֲנֶ֑ה וַיִּֽתְיַצְּב֖וּ בְּתַחְתִּ֥ית הָהָֽר׃ (יח) וְהַ֤ר סִינַי֙ עָשַׁ֣ן כֻּלּ֔וֹ מִ֠פְּנֵי אֲשֶׁ֨ר יָרַ֥ד עָלָ֛יו יְהוָ֖ה בָּאֵ֑שׁ וַיַּ֤עַל עֲשָׁנוֹ֙ כְּעֶ֣שֶׁן הַכִּבְשָׁ֔ן וַיֶּחֱרַ֥ד כָּל־הָהָ֖ר מְאֹֽד׃ (יט) וַיְהִי֙ ק֣וֹל הַשּׁוֹפָ֔ר הוֹלֵ֖ךְ וְחָזֵ֣ק מְאֹ֑ד מֹשֶׁ֣ה יְדַבֵּ֔ר וְהָאֱלֹהִ֖ים יַעֲנֶ֥נּוּ בְקֽוֹל׃
(16) On the third day, as morning dawned, there was thunder, and lightning, and a dense cloud upon the mountain, and a very loud blast of the horn; and all the people who were in the camp trembled. (17) Moses led the people out of the camp toward God, and they took their places at the foot of the mountain. (18) Now Mount Sinai was all in smoke, for the LORD had come down upon it in fire; the smoke rose like the smoke of a kiln, and the whole mountain trembled violently. (19) The blare of the horn grew louder and louder. As Moses spoke, God answered him in thunder.
(כח) בְּעַד֩ הַחַלּ֨וֹן נִשְׁקְפָ֧ה וַתְּיַבֵּ֛ב אֵ֥ם סִֽיסְרָ֖א בְּעַ֣ד הָֽאֶשְׁנָ֑ב מַדּ֗וּעַ בֹּשֵׁ֤שׁ רִכְבּוֹ֙ לָב֔וֹא מַדּ֣וּעַ אֶֽחֱר֔וּ פַּעֲמֵ֖י מַרְכְּבוֹתָֽיו׃
(28) Through the window peered Sisera’s mother, Behind the lattice she whined: “Why is his chariot so long in coming? Why so late the clatter of his wheels?”

(ט) אָמַר רַבִּי חֲנִינָא בַּר רַבִּי יִצְחָק כָּל יְמוֹת הַשָּׁנָה יִשְׂרָאֵל נֶאֱחָזִים בַּעֲבֵרוֹת, וּמִסְתַּבְּכִין בְּצָרוֹת, וּבְרֹאשׁ הַשָּׁנָה הֵן נוֹטְלִין שׁוֹפָר וְתוֹקְעִין בּוֹ וְנִזְכָּרִים לִפְנֵי הַקָּדוֹשׁ בָּרוּךְ הוּא וְהוּא מוֹחֵל לָהֶם, וְסוֹפָן לִגָּאֵל בְּקַרְנוֹ שֶׁל אַיִל, שֶׁנֶּאֱמַר: וַה' אֱלֹהִים בַּשּׁוֹפָר יִתְקָע.

R. Hanina b. R. Isaac said: Throughout the year Israel are in sin's clutches and led astray by their troubles, but on New Year they take the shofar and blow on it, and eventually they will be redeemed by the ram's horn, as it says, "And the Lord God will blow the horn."

(כ) וַיָּ֣רַע הָעָ֔ם וַֽיִּתְקְע֖וּ בַּשֹּֽׁפָר֑וֹת וַיְהִי֩ כִשְׁמֹ֨עַ הָעָ֜ם אֶת־ק֣וֹל הַשּׁוֹפָ֗ר וַיָּרִ֤יעוּ הָעָם֙ תְּרוּעָ֣ה גְדוֹלָ֔ה וַתִּפֹּ֨ל הַֽחוֹמָ֜ה תַּחְתֶּ֗יהָ וַיַּ֨עַל הָעָ֤ם הָעִ֙ירָה֙ אִ֣ישׁ נֶגְדּ֔וֹ וַֽיִּלְכְּד֖וּ אֶת־הָעִֽיר׃

(20) So the people shouted when the horns were sounded. When the people heard the sound of the horns, the people raised a mighty shout and the wall collapsed. The people rushed into the city, every man straight in front of him, and they captured the city.

(לט) וַיִּקַּח֩ צָד֨וֹק הַכֹּהֵ֜ן אֶת־קֶ֤רֶן הַשֶּׁ֙מֶן֙ מִן־הָאֹ֔הֶל וַיִּמְשַׁ֖ח אֶת־שְׁלֹמֹ֑ה וַֽיִּתְקְעוּ֙ בַּשּׁוֹפָ֔ר וַיֹּֽאמְרוּ֙ כָּל־הָעָ֔ם יְחִ֖י הַמֶּ֥לֶךְ שְׁלֹמֹֽה׃
(39) The priest Zadok took the horn of oil from the Tent and anointed Solomon. They sounded the horn and all the people shouted, “Long live King Solomon!”

(ח) וְסָפַרְתָּ֣ לְךָ֗ שֶׁ֚בַע שַׁבְּתֹ֣ת שָׁנִ֔ים שֶׁ֥בַע שָׁנִ֖ים שֶׁ֣בַע פְּעָמִ֑ים וְהָי֣וּ לְךָ֗ יְמֵי֙ שֶׁ֚בַע שַׁבְּתֹ֣ת הַשָּׁנִ֔ים תֵּ֥שַׁע וְאַרְבָּעִ֖ים שָׁנָֽה׃ (ט) וְהַֽעֲבַרְתָּ֞ שׁוֹפַ֤ר תְּרוּעָה֙ בַּחֹ֣דֶשׁ הַשְּׁבִעִ֔י בֶּעָשׂ֖וֹר לַחֹ֑דֶשׁ בְּיוֹם֙ הַכִּפֻּרִ֔ים תַּעֲבִ֥ירוּ שׁוֹפָ֖ר בְּכָל־אַרְצְכֶֽם׃ (י) וְקִדַּשְׁתֶּ֗ם אֵ֣ת שְׁנַ֤ת הַחֲמִשִּׁים֙ שָׁנָ֔ה וּקְרָאתֶ֥ם דְּר֛וֹר בָּאָ֖רֶץ לְכָל־יֹשְׁבֶ֑יהָ יוֹבֵ֥ל הִוא֙ תִּהְיֶ֣ה לָכֶ֔ם וְשַׁבְתֶּ֗ם אִ֚ישׁ אֶל־אֲחֻזָּת֔וֹ וְאִ֥ישׁ אֶל־מִשְׁפַּחְתּ֖וֹ תָּשֻֽׁבוּ׃

(8) You shall count off seven weeks of years—seven times seven years—so that the period of seven weeks of years gives you a total of forty-nine years. (9) Then you shall sound the horn loud; in the seventh month, on the tenth day of the month—the Day of Atonement—you shall have the horn sounded throughout your land (10) and you shall hallow the fiftieth year. You shall proclaim release throughout the land for all its inhabitants. It shall be a jubilee for you: each of you shall return to his holding and each of you shall return to his family.

(ג) הַֽ֭לְלוּהוּ בְּתֵ֣קַע שׁוֹפָ֑ר הַֽ֝לְל֗וּהוּ בְּנֵ֣בֶל וְכִנּֽוֹר׃
(3) Praise Him with blasts of the horn; praise Him with harp and lyre.
