Leviticus 23:18-26
English Standard Version
Chapter 23
18And you shall present with the bread seven lambs a year old without blemish, and one bull from the herd and two rams. They shall be a burnt offering to the Lord, with their grain offering and their drink offerings, a food offering with a pleasing aroma to the Lord. 19And you shall offer one male goat for a sin offering, and two male lambs a year old as a sacrifice of peace offerings. 20And the priest shall wave them with the bread of the firstfruits as a wave offering before the Lord, with the two lambs. They shall be holy to the Lord for the priest. 21And you shall make a proclamation on the same day. You shall hold a holy convocation. You shall not do any ordinary work. It is a statute forever in all your dwelling places throughout your generations.
23And 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.
25You shall not do any ordinary work, and you shall present a food offering to the Lord."
