The feasts of Israel are set according to Scripture. They are also called the appointed seasons of the Lord. They are actually a call for a formal assembly. The first of these come in the autumn and is Feast of Trumpets as recorded in Leviticus 23:23-25:
“And, the Lord said to Moses, “Say to the Israelites, on the first day of the seventh month (roughly, October), you shall observe a day of solemn (sabbatical) rest, a memorial day announced by blowing of trumpets, a holy, called assembly. You shall do no servile work on it, but you shall present an offering made by fire to the Lord.”
Elul is the Jewish month proceeding Rosh HaShanah or the Jewish New Year. This month is significant because it is month of self-examination and repentance in preparation the New Year. The bad deeds of the old year are weighed against the good deeds. Each person hopes his/her name will be inscribed in the Book of Life for another year. Things are made right between friends, family, and acquaintances. The ram’s horn or the shofar is blown at the end of morning prayers during this time and it is the custom to remember the poor by increasing giving to charities.
