5 The Lord's Passover begins at twilight on the fourteenth day of the first month. 6 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. 7 On the first day hold a sacred assembly and do no regular work. 8 For seven days present a food offering to the Lord. And on the seventh day hold a sacred assembly and do no regular work.' "
