Leviticus 23:33 MSG

[33] 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.
