What Is Rosh Hashanah in the Bible?

Rosh Hashanah, meaning 'head of the year,' is the Jewish New Year, observed on the first day of the month of Tishri (September or October). In the Bible, it is called the Feast of Trumpets (Yom Teruah), described in Leviticus 23:23-25 and Numbers 29:1-6. It was a day of rest, a 'memorial of blowing of trumpets,' and a holy convocation on which no customary work was to be done. The Feast of Trumpets served several purposes in Israel's religious life. First, it announced the beginning of the civil year and the seventh month, which was the most sacred month of the year, containing Yom Kippur and the Feast of Tabernacles. The trumpet blast called the people to prepare their hearts for the solemn days ahead. Second, it was a memorial — a call to remembrance. The sound of the trumpet reminded Israel of God's faithfulness, His covenant, and their obligation to live as His holy people. Third, the trumpet had prophetic significance. Throughout the Old Testament, trumpet blasts announced important events: the giving of the law at Sinai, the coronation of kings, the call to battle, and the proclamation of jubilee. The Feast of Trumpets anticipated the future day when God would gather His people with a great trumpet sound. In later Jewish tradition, Rosh Hashanah developed into a day of judgment. The rabbinic writings teach that on Rosh Hashanah, God opens the books of life and death, and during the ten days between Rosh Hashanah and Yom Kippur, people have the opportunity to repent and be inscribed for life. While this tradition is not in the biblical text, it reflects the deep spiritual significance of the day as a time of introspection and preparation. For Christians, the Feast of Trumpets carries rich typological significance. The trumpet is associated with the resurrection of the dead and the return of Christ. Paul wrote that 'the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first.' Jesus warned that His return would be sudden, 'as the lightning cometh out of the east, and shineth even unto the west.' The trumpet blast of Rosh Hashanah is a foreshadowing of that great and terrible day. The feast also points to the need for preparation. Just as Israel used the ten days between Rosh Hashanah and Yom Kippur to examine their lives and repent, so believers must live in constant readiness for Christ's return. 'Watch therefore: for ye know not what hour your Lord doth come.' The shofar, the ram's horn trumpet used on Rosh Hashanah, is itself a symbol of substitutionary sacrifice — recalling the ram that God provided in place of Isaac on Mount Moriah. Every blast of the shofar proclaims that God provides the sacrifice, that He calls His people to Himself, and that the day of reckoning is coming. Rosh Hashanah reminds us that life is short, judgment is certain, repentance is urgent, and the trumpet of redemption is sounding while there is still time to respond.
