Jewish New Year began with a blast—a trumpet blast (Num. 29:1-6, Lev. 23:23-25). People had a holiday and the priests made multiple sacrifices and blew a “remembrance signal” (teruah). It sounds like fun, but it was serious.
The Jewish religious year begins at Passover, celebrating the Exodus, but the civil year starts with plowing to prepare for new crops. Today the feast is called Rosh hashanah, “the head of the year”. It is a time of reflection—“What kind of harvest did I see from my life last year? How can I prepare the soil of my life to yield even more in the future?” Following Rosh hashanah are ten days of repentance or awe leading up to the Day of Atonement (Yom kippur). Those ten days are a period to prepare oneself to meet the Judge; they are an opportunity to repent and make a new start.
Resolutions don’t have to wait for New Year; if they are worth making, make them immediately. King Asa understood that. A prophet spoke to Asa, “If you seek [God], He will let you find Him” (2 Chron. 15:2). Asa removed idols, restored God’s altar and recommitted the nation to God. Then, with silver trumpets and horns (shofar), they resolved to seek God wholeheartedly (2 Chron. 15:8-15).
Later, after laying the foundations of the second temple, priests blew silver trumpets to praise God: “For He is good, for His loving-kindness is upon Israel forever” (Ezra 3:10-11).
The trumpet invites us to re-consecrate ourselves.
