וְכִֽי־תָבֹ֨אוּ מִלְחָמָ֜ה בְּאַרְצְכֶ֗ם עַל־הַצַּר֙ הַצֹּרֵ֣ר אֶתְכֶ֔ם וַהֲרֵעֹתֶ֖ם בַּחֲצֹצְר֑וֹת וֲנִזְכַּרְתֶּ֗ם לִפְנֵי֙ יְהוָ֣ה אֱלֹֽהֵיכֶ֔ם וְנוֹשַׁעְתֶּ֖ם מֵאֹיְבֵיכֶֽם׃
At kapag nakipagdigma kayo sa inyong lupain laban sa kalabang nagpapahirap sa inyo, hihipan ninyo nang paputol-putol ang mga trumpeta; at aalalahanin kayo sa harap ng Walang-Hanggan na inyong Diyos, at ililigtas kayo mula sa inyong mga kaaway.
Mishnah Rosh Hashanah
On [public] fast days they used shofars of rams, curved, the mouths of which were covered with silver, and there were two trumpets in between them. A short blast was made with the shofars and a long one with the trumpets, because the mitzvah of the day is with trumpets.
