Leviticus 23:4
3. Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; ye shall do no work therein: it is the sabbath of the LORD in all your dwellings.4. These are the feasts of the LORD, even holy convocations, which ye shall proclaim in their seasons.5. In the fourteenth day of the first month at even is the LORD'S passover.
