“And the Lord spoke to Moses, saying, “Speak to the children of Israel, and say to them: ‘The feasts of the Lord, which you shall proclaim to be holy convocations, these are My feasts. Six days shall work be done, but the seventh day is a Sabbath of solemn rest, a holy convocation. You shall do no work on it; it is the Sabbath of the Lord in all your dwellings. These are the feasts of the Lord, holy convocations which you shall proclaim at their appointed times.’” (Lev 23:1-4).
