Leviticus 23:3, 8, 21, 25, 35-36

“Six days shall work be done, but on the seventh day is a Sabbath of solemn rest, a holy convocation. You shall do no work. It is a Sabbath to the LORD in all your dwelling places.

But you shall present a food offering to the LORD for seven days. On the seventh day is a holy convocation; you shall not do any ordinary work.”

And 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.

You shall not do any ordinary work, and you shall present a food offering to the LORD.”

On the first day shall be a holy convocation; you shall not do any ordinary work. For seven days you shall present food offerings to the LORD. On the eighth day you shall hold a holy convocation and present a food offering to the LORD. It is a solemn assembly; you shall not do any ordinary work.
