Yom Hakeseh – The Hidden Day
Another idiom for the Feast of Trumpets is Yom HaKeseh – the Hidden Day.
Of all the feasts, Yom Teruah is the most mysterious one. There are few scriptures about it. The primary reference is Leviticus 23:23-25:
And the Lord spoke to Moses, saying, “Speak to the people of Israel, saying, In the seventh month, on the first day of the month, you shall observe a day of solemn rest, a memorial proclaimed with blast of trumpets, a holy convocation. You shall not do any ordinary work, and you shall present a food offering to the Lord.”
Yom HaKeseh, meaning “The Day of the Hiding” or “the Hidden Day.” It is the feast that is concealed as to when it starts. It can only start when the moon begins to reflect again. The New Moon of Tishrei is neither announced nor blessed in the synagogue. The term keseh or keceh is derived from the Hebrew root kacah, which means to “conceal, cover, or hide.” Every day during the month of Elul, a trumpet is blown to warn the people to turn back to G-d, except for the last day of Elul, the day preceding Rosh HaShanah (Elul 29 is known as the “Day of Release” at the end of a Shemita year.) On that day, the trumpet is not blown, because it was hidden from Satan, the adversary. It is taught that the Shofar does not blow on this day so that Satan does not know the day judgment begins.
Rosh HaShanah is concealed and shrouded in mystery. On this year (2015 or the first day of the Jewish New Year 5776), not only will the moon be hidden but the sun will also be hidden (partial solar eclipse on Sept. 13). The mystical aspect of Rosh HaShanah is indicated in Scripture: “Sound the shofar on the New Moon, in concealment of the day of our festival” (Psalm 81:3). The hiddenness of the day also goes along with what Jesus said in Matthew 24 “no man knows the day nor the hour.”
Psalm 27:5 reminds us:
“For in the time of trouble He shall hide me in His pavilion; in the secret of His tabernacle shall He hide me; He shall set me up upon a rock.”
