Don't work on that day because it is a day of atonement to make atonement for you before your God.
Anyone who doesn't fast on that day must be cut off from his people.
I will destroy from among his people anyone who works on that day.
Don't do any work that day - none. This is a perpetual decree for all the generations to come, wherever you happen to be living.
It is a Sabbath of complete and total rest, a fast day. Observe your Sabbath from the evening of the ninth day of the month until the following evening."
God said to Moses,
"Tell the People of Israel, God's Feast of Booths begins on the fifteenth day of the seventh month. It lasts seven days.
The first day is a sacred assembly; don't do any ordinary work.
Offer Fire-Gifts to God for seven days. On the eighth day hold a sacred assembly and offer a gift to God. It is a solemn convocation. Don't do any ordinary work
"These are the appointed feasts of God which you will decree as sacred assemblies for presenting Fire-Gifts to God: the Whole-Burnt-Offerings, Grain-Offerings, sacrifices, and Drink-Offerings assigned to each day.
These are in addition to offerings for God's Sabbaths and also in addition to other gifts connected with whatever you have vowed and all the Freewill-Offerings you give to God
