23:1 The LORD spoke to Moses, saying, 2 “Speak to the people of Israel and say to them, These are the appointed feasts of the LORD that you shall proclaim as holy convocations; they are my appointed feasts.

3 “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.
