Leviticus 23:6-8

6 And on the fifteenth* day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread.
7 In the first day ye shall have an holy convocation: ye shall do no servile work therein.
8 But ye shall offer an offering made by fire unto the LORD seven days: in the seventh day is an holy convocation: ye shall do no servile work therein.
