Blowing the Shofar

There are ten reasons for blowing the shofar, observing the ten day tradition of the High Holy Days:

Because this day is the beginning of creation, on which the Holy One, our G-d, created the world and reigned over it.
Because the day of the New Year is the first of the ten days of repentance, the shofar is sounded on it to announce to us as it warns and says: “Whoever wants to repent – let him repent and turn to G-d, the Creator.”
To remind us of Mt. Sinai. The sound of the shofar grew louder and louder (Ex. 19:19) and we should accept for ourselves the covenant that our ancestors accepted for themselves, as they said “we will do, and we will be obedient!” (Ex. 24:7).
To remind us of the words of the prophets that were compared to the sound of the shofar, as it is said “Then he who hears the sound of the shofar and does not take warning, and a sword comes and takes him away…but had he taken warning, he would have delivered his life.” (Ezek. 33:4-5).
To remind us of the destruction of the Temple and the sound of the battle cries of the enemies, as it is said “Because you have heard, O my soul, the sound of the shofar, the alarm of war.” (Jer. 4:19). When we hear the sound of the shofar, we are reminded of His Temple.
To remind us of the binding of Isaac. We should offer our lives to be sanctified through Y’Shua, and thus we will be remembered by G-d.
When we will hear the blowing of the shofar, we will be fearful, and we will tremble, and we will humble ourselves before the Creator, for that is the nature of the shofar. It causes fear and trembling, as it is written “If a shofar is blown in a city, will not he people tremble?” (Amos 3:6).
To recall the day of the Great Judgment and to be fearful of it, as it is written “Near is the great day of the L-rd. Near and coming very quickly … a day of shofar and battle cry….” (Zeph. 1:14-16).
To remind us of the ingathering of the scattered one of Israel, that we ardently desire, as it is said “It will come about also in that day that a great shofar will be blown: and those who were perishing the land of Assyria…will come and worship G-d in the holy mountain at Jerusalem.” (Isa. 27:13).
To remind us of the resurrection of the dead, the belief in it, as it is told “All you inhabitants of the world and dwellers on earth, a soon as a standard is raised on the mountains, you will see it, and as soon as the shofar is blown you will hear it.” (Isa. 18:30).
