Liturgy על ירמיהו 4:19

5) The shofar reminds us of the destruction of the Holy Temple which was destroyed amid the sounding of enemy trumpets, as it is said: כִּי קוֹל שׁוֹפָר שָׁמַעַתְּ נַפְשִׁי תְּרוּעַת מִלְחָמָה—“For you have heard the sound of the shofar, O my soul, the shouts of battle (Yirmiyahu 4:19); and when we hear the shofar on Rosh Hashana, we pray to God to restore the Temple to its former glory.
