Beginning at sundown tonight, practicing Jews observe Rosh Hashanah. It is 1Tishrei on the Jewish calendar, the first day of the month of Tishrei in the Hebrew calendar.
23 And the Lord spoke to Moses, saying, 24 “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. 25 You shall not do any ordinary work, and you shall present a food offering to the Lord.”Leviticus 23:23-25
It is also known as the Feast of Trumpets because of the blast of trumpets with which God told Moses the holy convocation should be proclaimed.
Some Biblical scholars believe that Jesus was born on 1 Tisheri of 3 BCE, rather than on the day most Christians celebrate His birth at Christmas. There is more on this topic than can be covered in this Blog post. I don’t know enough to know what to think of that but it seems plausible to me.
I also know there’s a long history of disagreement among Christians over whether Christians should (or can, if they want to) observe the Old Testament festivals and holidays. I’m not going to jump into that argument either.
But I do think it’s interesting to know something about the Jewish High Holy Days, because Jesus was Jewish, and as a practicing Jew He likely observed them.
