“ ‘These are the LORD’s appointed festivals, the sacred assemblies you are to proclaim at their appointed times: The LORD’s Passover begins at twilight on the fourteenth day of the first month. On the fifteenth day of that month the LORD’s Festival of Unleavened Bread begins; for seven days you must eat bread made without yeast. On the first day hold a sacred assembly and do no regular work. For seven days present a food offering to the LORD. And on the seventh day hold a sacred assembly and do no regular work.’ ” (- Lev. 23:4-8)
