The Biblical feast Rosh Hashanah, also known as the Jewish New Year, begins at sunset on Friday, Sept. 18. It ends at sunset on Sunday, Sept. 20. Yeshua (Jesus) hints in Matthew 24:36 that His Second Coming will occur during this window: “On that day and hour (Second Coming) no one knows, not even the angels of heaven, but My Father only.”
His Jewish audience likely made the connection. Rosh Hashanah is the only Biblical feast that starts on the first day of a Hebrew month. In Biblical times the start of each month was determined by the sighting of a new moon. Jews had a two-day window to watch for the new moon. No one knew the day or hour it would appear.
Rosh Hashanah also is called the Feast of Trumpets. The apostle Paul says in 1 Corinthians 15:51-52 the rapture of the church will coincide with the blowing of a trumpet or shofar (ram’s horn): “Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed – in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed.” We don’t know what year Yeshua will come back. But we can know the season.
