Numbers 29:1, 12, 35

“Celebrate the Festival of Trumpets each year on the first day of the appointed month in early autumn. You must call an official day for holy assembly, and you may do no ordinary work.

“Five days later, on the fifteenth day of the same month, you must call another holy assembly of all the people, and you may do no ordinary work on that day. It is the beginning of the Festival of Shelters, a seven-day festival to the LORD.

“On the eighth day of the festival, proclaim another holy day. You must do no ordinary work on that day.
