In the first day ye shall have an holy convocation: ye shall do no servile work therein.
Numbers 28:18-25
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 savour 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.
