4 These are the set feasts or appointed seasons of the Lord, holy convocations you shall proclaim at their stated times: 5 On the fourteenth day of the first month at twilight is the Lord's Passover. 6 On the fifteenth day of the same month is the Feast of Unleavened Bread to the Lord; for seven days you shall eat unleavened bread. 7 On the first day you shall have a holy "calling together;" you shall do no servile or laborious work on that day. 8 But you shall offer an offering made by fire to the Lord for seven days; on the seventh day is a holy convocation; you shall do no servile or laborious work on that day.
