Rosh HaShana- The Shofar of the Redemption

Before beginning this study, we need to take bearings on the role this festival has in Judaism and why it was called the Head of the year, Rosh Hashana הַשָּׁנָה רֹאשׁ.

Rosh Hashana is actually the Festival of the Trumpets mentioned twice in the Torah: in the Parasha Emor and in Pinchas:
Leviticus 23:24-25 Speak to the children of Israel, saying: ‘In the seventh month, on the first day of the month, you shall have a sabbath-rest, a memorial of blowing of trumpets, a holy convocation. You shall do no customary work on it; and you shall offer an offering made by fire to the Lord.’”
