Leviticus 23:7

In the first day shall be an holy convocation; ye shall do no manner of servile work therein: But ye shall offer a sacrifice made by fire for a burnt offering unto the LORD; two young bullocks, and one ram, and seven lambs of the first year: they shall be unto you without blemish: And their meat offering shall be of flour mingled with oil: three tenth deals shall ye offer for a bullock, and two tenth deals for a ram; A several tenth deal shalt thou offer for every lamb, throughout the seven lambs: And one goat for a sin offering, to make an atonement for you. Ye shall offer these beside the burnt offering in the morning, which is for a continual burnt offering. After this manner ye shall offer daily, throughout the seven days, the meat of the sacrifice made by fire, of a sweet savor unto the LORD: it shall be offered beside the continual burnt offering, and his drink offering. And on the seventh day ye shall have an holy convocation; ye shall do no servile work.
