Leviticus 23:30-35

³⁰I will destroy anyone of you who does any work on this day.

³¹Don't do any kind of work at all. This regulation is for all time and for future generations everywhere you live.

³²It is to be a Sabbath of complete rest for you, and you shall practice self-denial. You are to observe your Sabbath from the evening of the ninth day of the month until evening the next day.”

³³The Lord told Moses,

³⁴“Tell the Israelites that the Feast of Tabernacles to honor the Lord begins on the fifteenth day of the seventh month and lasts for seven days.

³⁵On the first day have a holy meeting. You must not do any of your usual work.
